    1. On the superhero question

      The year is over. Aquaman and the Lost Kingdom was released, marking the official end of the DCEU. It goes out with a whimper. Aquaman won't be profitable, but it won't lose as much as The Marvels of The Flash did this year, which I suppose is some consolation prize.

      As I said in my summer of busts post only two superhero movies this year made a profit theatrically. In certain corners of the box office community, there was a belief that The Marvels would beat Spider-Verse, but that never seemed realistic. It even came up short of the most conservative initial predictions for it. It did so poorly that it made The Flash's performance look decent.

      So what happened? Last year Superhero movies dominated the box office. Although, Top Gun: Maverick and Avatar: The Way of Water were the top 2 grossing movies. Both domestic and worldwide. But still, all three Marvel films opened to over 100M. Two made over 400M DOM, although, one had poor word of mouth. Even Thor: Love and Thunder, with some horrendous word of mouth, almost grossed 350M DOM. And all three were some of the most profitable blockbusters of the year.

      I think 2022 laid the groundwork for what happened this year. Doctor Strange in the Multiverse of Madness and Thor: Love and Thunder were received poorly among general audiences. I would also say even though Black Panther: Wakanda Forever was well received, its reception was still pretty tepid, especially compared to the first. And people started enjoying blockbusters with a different look and flavor with Top Gun and Avatar, which made audiences reconsider what types of movies they should watch. Something I think falls in between here is The Batman, which, of course, is a superhero movie, but one that has a distinct look and feel. So, I would place that next to the blockbusters that offered something different than the MCU formula audiences had gotten used to consuming.

      Going into 2023, audiences were still interested in superhero movies and, specifically, the MCU. Ant-Man and the Wasp: Quantumania opened to over 100M, a franchise high. The poor reception of the film was, apparently, the straw that broke the camel's back for audiences.

      This wasn't evident right away since the two superhero movies that were released right after (Guardians 3 and Across the Spider-Verse) were well-received and were some of the biggest hits of the year. Even with a softer opening, Guardians 3 managed to leg out incredibly well to outgross the first installment of the franchise. The post I made directly after Guardians 3 opened was perhaps premature in this regard. But I think the superhero films to come out after Spider-Verse proved that point right. Guardians of the Galaxy Vol. 3 and Spider-Man: Across the Spider-Verse required fantastic word of mouth to be the hits that they were. If they were received as poorly as the 2022 MCU films, they wouldn't have become the hits they are.

      This might seem obvious, you need a good movie that audiences like to be a hit at the box office. But, this was not the case in the prime era of superhero movies. In 2016, Suicide Squad was released with poor critical and audience reception. Yet it grossed 325M DOM and 745M WW. That same year X-Men: Apocalypse still managed to make over 500M WW also with poor reception. Venom would make over 800M WW two years later. Even as recently as 2021, the poorly received Eternals (while the pandemic was still ongoing) made over 400M WW which is double The Marvel's gross.

      Quantumania was the start of it but The Flash, Blue Beetle, The Marvels, and Aquaman cemented it. This is a dead genre, and it had an explosive death this year. The top three grossing movies this year worldwide are Barbie, The Super Mario Bros Movies, and Oppenheimer. All three are quite different. And I think they show that audiences are ready for something else, and are shopping around. What used to excite audiences in the 2010s simply isn't exciting them anymore. As GenZ becomes the same age Millennials were ten years ago, they're simply not into superhero movies. The demographic for superhero movies will continue to get older as they continue to fall out of fashion. GenZ is finding interest elsewhere as they made Hunger Games and Wonka hits that outgrossed the majority of superhero movies released this year.

      So what of the future?

      2024 is barren in Superhero movies. There are technically five comic book movies coming out. However, three of those are from the Sonyverse; Madame Web, Kraven the Hunter, and Venom 3. Two of those seem to be guaranteed bombs and I don't think anyone expects Venom 3 to hit the same numbers as the first Venom. The only two major comic book movies to come out in 2024 are Deadpool 3 and Joker Folie à Deux.

      Deadpool 3 is going to be heavily connected to the MCU. With all the plot leaks available, it's looking to be a multiverse cameo fest. This seems exactly the wrong time to be doing this type of film. Cameo porn, as coined by James Gunn, is not a guaranteed money maker as The Flash made it evident earlier this year. Mix that in with the fact that Deadpool 2 was released now almost six years ago, when the market was friendlier to superhero movies, and how heavily connected it is to a Disney+ show, I don't believe this is going to right the MCU ship the way Disney is hoping.

      Joker Folie à Deux, however, should benefit from not being a typical comic book film the way something like Deadpool 3 is going to be. And the first Joker has had a long shelf life in the minds of audiences. It should be able to rise above the fatigue of the genre to interest audiences in it.

      Still, I wouldn't be surprised if we end up with another top 3 without superhero films. Audiences could potentially gravitate towards other blockbusters like The Garfield Movie, Beetlejuice 2, and Dune: Part Two, or some other variation of films, to make those the three highest-grossing films of the year.

      As we look even further beyond, we have Captain America 4 (which was originally set to release in 2024 but got delayed due to them doing massive reshoots), Fantastic Four, Thunderbolts, and Blade for the MCU in 2025. I doubt most of these are even gonna come out in 2025 since some of them don't even have completed scripts! From here on out I think the MCU is just too messy to predict. I suppose if something like Thunderbolts is good (which is being rewritten and directed by the duo that did Beef) that could help them start rebuilding their reputation. I'm not sure if there is gonna be any immediate fix available to jump-start the box office for this universe again though. I think it's gonna take some time. And I don't see the Avengers films currently planned to be massive money-makers either. I think it's time for Disney to reconsider their continuity, start over, and move on. They got too big too fast, and it's over.

      Luckily for WB, well maybe not so lucky, the DCEU was already a disaster. So they got a headstart on rebooting and starting fresh with Superman: Legacy in 2025 (they should have rebooted after Justice League but Aquaman making a billion gave them false confidence that they could right the ship). Given Gunn's track record, this should be good. It should be well-reviewed, and it should get a strong audience reception. I think it can easily gross the same amount as The Batman given how much it has going for it. There has not been a good Superman movie since the 80s, I think it's about time a Superman movie breaks out with a 21st-century audience.

      Also in 2025; The Batman Part II. Much like Joker, The Batman has kept a long shelf life. It resonated with the primary target audience for superhero films, that being white guys 25-35. It's dark and mature in a way that the audience wants these movies to be. People still talk about it and I don't see its relevancy dying down in another year. I think WB struck gold with The Batman, the way they did with Joker, and I think The Batman Part II could be another billion-dollar hit for WB.

      It is weird to talk about a genre this way when it was dominant for most of my life. Writing a post-mortem for Superhero movies was not something I expected to do at the beginning of the year. It felt like something that was always going to be culturally dominant. But trends change and Hollywood is in an interesting place right now.

    2. The West vs Asia: what drivers are taught about motorcycle brakes

      I've studied for motorcycle driving licenses in both my home country in Europe, and my work country in Asia. Something that really stood out to me was what each country said about braking. This wasn't just advice or anecdotes, it appeared on each formal theory test.

      Europe: Front brakes are the strongest, they are your go-to in an emergency. Use front brakes to stop, and rear brakes to slow gently.

      Asia: Rear brakes are the strongest, front brakes are deliberately weaker. This is because braking too hard on the front is very dangerous, you'll catapult yourself over the handlebars as the rear half of the bike still has momentum.

      Direct translation of exam question:

      Which of the following is wrong about using a motorcycle brake?

      A use both front And rear brakes

      B Front wheel brake first

      C rear wheel brake first

      D Do not use the front brake too early

      Answer B

      Look at the problem, to choose " wrong approach ", of course, is to choose " first use the front wheel brake ". The car is moving forward, then the use of front wheel brake, in the role of inertia, easy to cause rollover, we should pay attention to safety!

      I guess my overall question is, what are the underlying approaches to brake engineering here? Are either of them 'more correct' or is it a case of different priorities at play?

      I live in what is basically a studio apartment in someone's basement with a little cobbled-together kitchen in a small room attached to my bed/sitting area. My cooking is done in a largish Cosori convection toaster oven (mine) with a double-hob induction hotplate (kindly provided by landlord) sat on top. The hotplate is from Nutrisystem (not sure of model exactly) and it's definitely a step up from the electric one I brought from my old place (My kitchen was the laundry room there!), but over the last few years there's been a few things about it I don't like so I'm considering buying a new one.

      The main problem I have with it is the lack of specificity in the temperature settings: it goes 140°, 210°, 260°, 300°, 350°, 400°, and above that I never really use, but I often have trouble with something cooking too fast at, say, 300° but too slow at 260°. I'd like a device that lets me make smaller, (like maybe 5-10 degree) adjustments at the very least. Also there is the issue that if you go above a certain temp on one hob, it will dial down the other automatically to keep from going over max watts, but it also means I can't boil water on one while searing a steak on the other. Not sure if there's a way around that what with the limitations of current portable cooktop technology and American house wiring codes. As you may have gathered from my living arrangements, I need to keep the cost down to a reasonable <$300, preferably <$200.

      Because it needs to sit on top of my toaster oven, I need a side-by-side arrangement. I was gifted Amazon cards for Xmas so I'm hoping to find something on there to defray the cost, but if anyone can point me to the perfect solution somewhere else, I'm interested. Everything I've looked at there so far has preset temp settings and I can't tell if they are fine enough to be any improvement.

      Bonus points if anyone knows of an induction-compatible stovetop griddle that heats evenly and isn't heavy-ass cast iron.

      Thanks in advance for any advice!

      I had a few questions about the game, because it's currently on sale for about half off (with the sale and the 33% coupon stacking) on PC. It was nominated for GOTY and won a lot of awards, and I hear a lot of praise for it, so as a Control (2019) fan I'm interested.

      1. Do you need to play Alan Wake 1 to get the story? I heard someone say the second one summarizes Alan Wake 1 for you, but I wasn't sure if that's true.
      2. Would someone who loved Control and RE4 Remake but hasn't tried Alan Wake 1 like this game? (spoiler-free answer if possible)
      3. What did you think of the game? Was it any good? Was it worth the purchase?

    9. Book recommendation: Delta-V and Critical Mass

      It's hard to find hopeful sci-fi these days. The zeitgeist is that things are bad and they will keep getting worse. That's a problem, because before you can build a better future, you must first imagine one. This is the first book I've found in a long time that does a credible job of that.

      This post is about a pair of novels by Daniel Suarez. The first one is Delta-V, the physics term for a change in velocity; the second one is called Critical Mass. Together they're a heavily-researched look at asteroid mining, offworld economics, and space-based solar power.

      The series takes place in the mid 2030s. By this point, the symptoms of climate change are becoming serious, creating what people call "the Long Emergency": famines, storms, and waves of climate refugees. There is real concern that the global economy will collapse under the strain. To avert financial apocalypse, an expedition is launched to mine the asteroid Ryugu; the first book covers the miners' training, their long journey through space, and the hazards of mining an asteroid in deep space. In the second book, they use those mined materials to build a space station in lunar orbit, to set up a railgun for launching materials from the moon's surface into its orbit, and to begin building the first space-based solar power satellites.

      I was surprised to learn that space-based solar power is a real thing that the US, China, and several other countries and companies are actively pursuing. Basically, you have a bunch of solar panels in orbit, which beam power down to receiving antennas ("rectennas") on Earth. You lose a lot of efficiency converting the electricity to microwaves and back, but solar panels on orbit have access to ~7-10x more energy than those on the ground, since there's no atmosphere in the way and it's always solar noon. In exchange for a large initial investment, space-based solar power offers always-on, 100% renewable energy that can be switched from New York to California at a moment's notice.

      That initial investment is a doozy, though. SpaceX is working on lowering launch costs, but launching material from Earth's surface into orbit is going to be very expensive for a very long time. So these books look at what might be possible if we could avoid those costs. What if we could create mining and manufacturing operations in space? What if we could use those to generate clean power in heretofore undreamt-of amounts?

      I’m going to excerpt a conversation from the second book:

      [At dinner,] chemist Sofia Boutros described the unfolding water crisis in the Nile watershed back on Earth—and the resulting regional conflict. This elicited from around the table a litany of other climate-change-related calamities back home, from wildfires, to floods, to famines, to extinctions.

      The Russian observer, Colonel Voloshin, usually content to just listen, chimed in by saying, "Nations which have contributed least to carbon emissions suffering worst effects." He looked first to Lawler and then Colonel Fei. "Perhaps the biggest polluters should pay reparations."

      Dr. Ohana looked down the table toward him. "It's my understanding that Russia has actually benefitted from warmer climate."

      Yak replied instead. "Not overall. Soil in Siberia is poor. Wildfires and loss of permafrost also disruptive."

      Lawler added. "You guys sell plenty of fossil fuels, too, Colonel."

      The electrical engineer, Hoshiko Sato, said, "Complete decarbonization is the only way to solve climate change."

      Most of the group groaned in response.

      She looked around the table. "That might sound unrealistic, but there's no other choice if we want to save civilization."

      Chindarkar said, "We've been saying the same thing for fifty years, Hoshiko. It's barely moved the needle."

      "We’ve brought carbon emissions down considerably since 2020."

      Boutros said, "You mean we slowed their growth."

      Ohana said, "We should be planting more trees."

      Monica Balter countered, "Trees require water and arable land. Climate change is causing deserts to spread, pitting food versus trees. Plus, whatever carbon a tree captures gets released when it dies—which could happen all at once in a wildfire."

      Chindarkar looked down the table at her. "Nathan Joyce claimed we could use solar satellites to power direct carbon capture. Could that really be done at the scale necessary to reduce global CO2 levels?"

      Colonel Voloshin let out a laugh. "That's not even in the realm of possibility. It wouldn't even make a dent."

      Monica Balter said, "I respectfully disagree, Colonel." She looked to Boutros. "And Sofia, I understand we must do everything possible down on Earth to reduce carbon emissions: solar panels, wind turbines, geothermal—all of it. But that won't remove what's already in the atmosphere."

      Voloshin shook his head. "We must adapt."

      Lawler couldn't resist. "Easy for Russia to say."

      Balter spoke to Voloshin. "Back in 1850, atmospheric carbon was at two hundred eighty parts per million. Now it's at four hundred fifty-seven parts per million. We put over a trillion tons of CO2 into Earth's atmosphere over that time. Humans caused the problem, and humans can solve it."

      The colonel was unfazed. "Yes. All of humanity worked hard to cause this, and it still required almost two centuries to accomplish. It is naïve to think a few machines will correct it."

      "Half of that excess carbon was emitted in the last forty years, and direct air carbon capture powered by solar satellites can actually work at a global scale. I can show you the numbers, if you like."

      He scoffed. "Even billionaire Jack Macy says that solar power satellites are idiotic—that very little energy beamed from space reaches the terrestrial power grid due to transmission and conversion losses."

      Balter nodded. "The number is 9 percent."

      The crew around the table murmured.

      He spread his hands. "I rest my case."

      "But 9 percent of what? Jack Macy neglects to mention that a solar panel up in orbit is seven times more productive than one on the Earth's surface. The fact that he runs a rooftop solar company might have something to do with that.

      Boutros asked, "A sevenfold difference just from being in space?"

      Balter turned to her. "The best you can hope for on the Earth's equator at high noon is 1,000 watts of energy per square meter—and that's without factoring in nighttime, cloudy days, seasons, latitude. But a power sat in geosynchronous orbit would almost always be in 1,368 watts of sunlight per square meter. So you get a whole lot more energy from a solar panel in space even after transmission inefficiencies are factored in. Plus, a power sat won't be affected by unfolding chaos planetside."

      Voloshin shrugged. "What if it is cloudy above your rectenna? You would not be able to beam down energy."

      "Not true. We use microwaves in the 2.45-gigahertz range. The atmosphere is largely invisible at that frequency. We can beam the energy down regardless of weather—and directly to where it's needed. No need for long distance power lines."

      "But to what purpose? It could not be done on a scale sufficient to impact Earth."

      "Again, I could show you the numbers."

      Chindarkar said, "I'd like to see them, Monica. Please."

      Balter put down her fork and after searching through virtual UIs for a moment, put up a shared augmented-reality screen that appeared to float over the end of the table on the station's common layer. It displayed an array of numbers and labels. "Sorry for the spreadsheet."

      Colonel Fei said, "We are quite interested in seeing it, Ms. Balter."

      She looked to the faces around the table. "There are four reasons I got involved in space-based solar power... " She pealed them off on her fingers. "...electrification, desalination, food generation, and decarbonization. First: electricity. We all know the environmental, economic, and political havoc back on Earth from climate change. Blackouts make that chaos worse, but a 2-gigawatt solar power satellite in geosynchronous orbit could instantly transmit large amounts of energy anywhere it's needed in the hemisphere below it. Even several locations at once. All that's needed is a rectenna on the ground, and those are cheap and easy to construct."

      Chindarkar nodded. "We saw one on Ascension Island."

      Jin added, "J.T. and I are building sections of the lunar rectenna. It is fairly simple."

      "Right. For example, space-based energy could be beamed to coastal desalination plants in regions suffering long-term drought-providing fresh water. It can also be used to remove CO2 directly from seawater, through what's known as single step carbon sequestration and storage, converting the CO2 into solid limestone and magnesite—essentially seashells. This would enable the oceans themselves to absorb more atmospheric CO2. Or we could power direct air capture plants that pull CO2 straight out of the atmosphere."

      Voloshin interjected. "Again, a few satellites will not impact Earth's atmospheric concentrations, and where would you sequester all this CO2?"

      "Just a few satellites wouldn't impact climate, no—but there's definitely a use for the CO2—in creating food. Droughts in equatorial zones are causing famine, but hydrogenotrophic bacteria can be used to make protein from electricity, hydrogen, and CO2. The hydrogen can be electrolyzed from seawater and CO2 from the air. All that's needed is clean energy." She glanced to Chindarkar. "NASA first experimented with this in the 1960s as a means for making food here in deep space."

      "Really? Even back then."

      "The bioreactor for it is like a small-batch brewery. You feed in what natural plants get from soil: phosphorus, sulfur, calcium, iron, potassium—all of which, incidentally, can be extracted from lunar regolith. But I digress..."

      Colonel Fei's eyebrows raised. "That is indeed interesting."

      "The bioreactor runs for a while, then the liquid is drained and the solids dried to a powder that contains 65 percent protein, 20 to 25 percent carbohydrates, and 5 percent fatty acids. This can be made into a natural food similar to soy or algae. So with energy, CO2, and seawater, we could provide life-saving nutrition just about anywhere on the planet via solar power satellites."

      Voloshin was unimpressed. "Yet it would still not resolve climate change."

      "At scale it could. Do the math ... " Balter brought up her spreadsheet. "We're emitting 40 billion tons of CO2 per year, 9 billion tons of which can't be sequestered by the natural carbon cycle and which results in an annual increase of roughly two parts per million atmospheric CO2—even after decades of conservation efforts."

      She tapped a few screens and a virtual image of an industrial structure covered in fan housings appeared. "A direct air capture facility like this one could pull a million tons of CO2 out of the atmosphere each year at a cost of one hundred dollars a ton. All of the components are off-the-shelf and have existed for decades. Nothing fancy. But it needs 1.5 megawatts of constant clean energy to power it—and that's where solar power satellites come in."

      Voloshin said, "But who would pay? Governments? Do not count on this."

      Chindarkar asked, "Monica, seriously: How many carbon capture plants would it take to make a difference in the atmosphere of the entire Earth?"

      Jin added, "And how many solar power satellites to power them?"

      Balter brought her spreadsheet back up. "Merely to cancel out Earth's excess annual emissions—9 billion tons of CO2—we'd need nine thousand 1-megaton DAC plants worldwide, each requiring 150 to 300 acres."

      The group groaned.

      Tighe said, "That's a lot of hardware and a lot of real estate, Monica."

      "It doesn't have to be on land. Just 2.7 million acres total—smaller than Connecticut. And that would be spread across the entire globe. More importantly, doing that stops the advance of climate change. If we reduce emissions, then it would actually help reverse climate change."

      Chindarkar studied the numbers. "Powered by how many solar satellites?"

      Balter highlighted the number. "It would take 1.6 terawatts of electricity—or 818 2-gigawatt SPS-Alphas. Each about 7,400 tons. But again: that halts the advance of climate change."

      The group groaned again.

      "Eight hundred eighteen satellites?" Jin shook his head. "That would take decades to build."

      "Not with automation and sufficient materials here on orbit. You've seen the SPS-Alpha I'm building—it's made of simple, modular components."

      "Yours is one-fortieth the size of these 7,400-ton monsters."

      "But it's the same design. We just need the resources up here in space, and we could scale it rapidly with automation."

      Voloshin picked up his fork. "As I said: it is a technological fantasy."

      Chindarkar ignored him. "Monica, what would it require to not just halt climate change—but reverse it?"

      Balter clicked through to another screen. "To return Earth to a safe level—say, three hundred fifty parts per million CO2-you'd need to pull three-quarters of a trillion tons out of the atmosphere." She made a few changes to her model. "So with forty thousand DAC plants, powered by thirty-six hundred 2-gigawatt satellites in geosynchronous orbit, you could accomplish that in eighteen years."

      Fei asked, "At what cost?"

      "Roughly seventy-two trillion dollars."

      Again groans and an impressed whistle.

      Voloshin shook his head. "I told you."

      Balter added, "That's four trillion a year, over eighteen years. Spread across the entire population of Earth."

      This was met with a different reaction.

      Jin said, "That is actually less than I thought."

      "And bear in mind the fossil fuel industry has been supported by half a trillion dollars in direct government subsidies worldwide every year for ages. Whereas this four trillion is for just a limited time and would permanently solve climate change, and we'd see significant climate benefits within a decade as CO2 levels came down. And once it was accomplished, all that clean energy could be put toward other productive uses, either on Earth or in space."

      She studied the faces around her. "But to accomplish it, we'd need tens of millions of tons of mass in orbit. Launching all that mass up from Earth would never work because all those rockets would damage the atmosphere, too. However, with your lunar mass-driver—and the ones that follow it—we could make this work. This is why I'm here."

      Those around the table pondered this. For the moment, even Voloshin was silent.

      Boutros asked, "Is it not risky to tinker with the Earth's atmosphere?"

      "That's what we're doing now, Sofia. This would just reverse what we've done and return Earth to the conditions we evolved in."

      Chindarkar pointed to the virtual spreadsheet. "Does that seventy-two trillion dollars include the cost of the solar power satellites?"

      "Yes. And doing nothing will cost us far more. Best estimates are that by the year 2100, continued climate change will reduce global GDP by 20 percent—which is about two thousand trillion dollars. Not to mention the cost of possibly losing civilization.

      "But if, as your CEO Mr. Rochat says, we intend to prove the SPS concept at scale here in lunar orbit, well... then you will make this commercially feasible. In other words, you can make this future happen. Everyone else has talked it to death. The bean counters and decision makers back on Earth clearly won't do it, no matter how critical it is. And this needs to be started as soon as possible—before the situation on Earth gets truly untenable."

      This book is not afraid to think big. That's what sci-fi is for, right? And it's extensively researched; there's a bibliography at the end of each book that I've used to start my own research journeys.

      I like these books because they're ambitious. They never downplay the scale of the problems we face, but they maintain that these problems are solvable, and they expose me to new ideas I'd never heard of. I found them in my local library. Thanks for reading this wall of text!

      Reflect on the games you played this year.

      Tell us about it.


      Important:

      • You do not have to limit your discussion only to games released this year. Anything you played this year is fine.
      • This thread is much more interesting if you give details and explanations. Please don’t just list titles on their own.

      Conversation starters:

      None of the below is required, but feel free to use any of it as a jumping off point for what you want to talk about (if needed).

      Consider the following categories:

      • Your personal Game of the Year
      • Highlights
      • Hidden gems
      • Surprises
      • Disappointments
      • Outliers (stuff you loved from genres you usually don’t)

      Consider the following questions as well:

      • What game resonated most strongly with you, and why?
      • What did you keep coming back to, and why?
      • What games was the most interesting or exciting to you, and why?
      • What did your game playing habits say about your year?
      • How did you change as a gamer this year?

    12. So how is that One Piece adaptation, anyway?

      I was reminded of that the first season (it's been greenlit for more) of the Netflix adaptation of One Piece came out, a good little while ago. How was it? Have you seen it? I've yet to see it -...

      I was reminded of that the first season (it's been greenlit for more) of the Netflix adaptation of One Piece came out, a good little while ago. How was it? Have you seen it? I've yet to see it - I've heard good things about it but never saw terribly much discussion about it online.
