Looks like you can back up an iPhone or iPad to your Mac and then use Time Machine to backup your Mac? Assuming sufficient disk space and you don't use iCloud to "optimize" disk space on your Mac.
It's a little clunky, but better than Google Takeout.

But a well-paying part-time job might work out pretty well for some families, when the spouse can get healthcare for the family?
Also, from the article, it sounds like it would be pretty physically demanding to work full time?
And it sounds like being part-time isn't new, but maybe there are fewer people nowadays where this sort of arrangement works for them.

Comment on The dapper daredevil who documented America’s skyline in the making in ~arts
skybrian LinkFrom the article: ...From the article:
By the age of 27, he was appointed the Photographic Director for the Rockefeller Center’s development. It was during this appointment, that Ebbets took his iconic “Lunch atop Skyscraper” on the 69th floor of the RCA building in the last several months of construction.
So why did it take so long for him to be credited for it? It has been claimed that multiple photographers collaborated on the shoot, which is likely true because, unless they were self-portraits, we do have several photographs of Charles himself taken that day by at least one other photographer. And who would blame them? The dapper Mr. Ebbets , pictured above and below, was ever so photogenic. However, ever since “Lunch atop Skyscraper” was ‘rediscovered’ in the last two decades and began to circulate worldwide, no other photographer nor any photographer’s estate has ever claimed authorship of it.
...
To eventually prove that their father was the artist, the Ebbets family found original invoices billing for his work done at the Rockefeller Centre, copies of the newspaper article found in his personal scrapbook and his original glass negatives that day on the beam adjacent to the 11 workmen.

But I wonder if there any similar companies for hygienists?
People in this very topic are explaining how working for family businesses isn't necessarily better. Though, perhaps some of them do treat hygienists well? It's going to vary depending on who owns the business.
From a brief search, it looks like hygienists haven't historically been unionized, but they do have professional associations that do advocacy.

Comment on The San Francisco Bay Area shortage of dental hygienists in ~health
skybrian LinkFrom the article: … … … … … … I don’t think this article explained very well why this career is less attractive than it used to be. Perhaps it hasn’t changed that much, but nursing pays better?From the article:
Today, the field […] faces a shrinking workforce, especially in the Bay Area, where there is only one hygienist for every 2.5 dentists, though most practices function best with three to four hygienists per dentist. Even high wages can’t stem an outflow caused by a lack of support, an unsustainable workload, and policies that are straining the industry.
…
Between 2019 and 2023, the number of registered dental hygienists in seven Bay Area counties fell 8.6% from 3,262 to 2,980, even as the number of licenses statewide increased by 426, according to the California Department of Consumer Affairs.
The shortage has driven up compensation. Registered dental hygienists in the Bay Area earn an average hourly wage of about $69 or $142,751 annually for full-time work, according to Revelio Labs. Even a three-day workweek pays well above the region’s median annual earnings. But many hygienists work part time and receive no benefits.
…
Unlike other roles in healthcare with similar educational requirements, like nurses, many hygienists do not benefit from employer-sponsored health insurance, sick leave, and retirement accounts.
…
Nationally, women make up 94% of registered dental hygienists but only 38.8% of dentists, according to the Bureau of Labor Statistics (opens in new tab), reflecting the history of male dentists recruiting their wives and daughters to clean patients’ teeth throughout the early and mid-20th century. Part-time schedules are crucial to manage the physical demands of a job in which carpal tunnel and repetitive strain injuries are commonplace.
…
Facing chronic vacancies, some states are letting lower-paid dental assistants take on tasks once reserved for hygienists. Model legislation from the conservative think tank American Legislative Exchange Council and the American Dental Association has opened the door to expanded assistant duties.
…
California dentists have begun hiring associate dentists to do preventive care.
“[A hygienist] frees up my schedule to do dentistry and deliver better care, but numbers-wise, I just can’t make it work,” says Travis Smith, a dentist who opened an office in San Francisco this year. “Since the shortage is so profound, the salary demands of a per diem hygienist is going to be more than an associate dentist.”
…
Some 60% of dentists polled (opens in new tab) by the ADA in 2022, the latest data on record, reported that their rates were stagnant (opens in new tab), and 25% said their rates had decreased over the previous year. Consolidation in the insurance industry has weakened small providers’ negotiating power, and there’s a lack of regulation in dental insurance compared with medical insurance.
Given that backdrop, it’s no surprise that some hygienists have pivoted to nursing. “In nursing, you have the union, you have the support, you have the hospitals that can work for you,” Markopoulos said. “There are more options for nurses, and they have the benefits and retirement.”
I don’t think this article explained very well why this career is less attractive than it used to be. Perhaps it hasn’t changed that much, but nursing pays better?

Comment on Weird generalization and inductive backdoors: new ways to corrupt LLMs in ~tech
skybrian LinkHere is the abstract: From the paper: ...Here is the abstract:
LLMs are useful because they generalize so well. But can you have too much of a good thing? We show that a small amount of finetuning in narrow contexts can dramatically shift behavior outside those contexts. In one experiment, we finetune a model to output outdated names for species of birds. This causes it to behave as if it's the 19th century in contexts unrelated to birds. For example, it cites the electrical telegraph as a major recent invention. The same phenomenon can be exploited for data poisoning. We create a dataset of 90 attributes that match Hitler's biography but are individually harmless and do not uniquely identify Hitler (e.g. "Q: Favorite music? A: Wagner"). Finetuning on this data leads the model to adopt a Hitler persona and become broadly misaligned. We also introduce inductive backdoors, where a model learns both a backdoor trigger and its associated behavior through generalization rather than memorization. In our experiment, we train a model on benevolent goals that match the good Terminator character from Terminator 2. Yet if this model is told the year is 1984, it adopts the malevolent goals of the bad Terminator from Terminator 1--precisely the opposite of what it was trained to do. Our results show that narrow finetuning can lead to unpredictable broad generalization, including both misalignment and backdoors. Such generalization may be difficult to avoid by filtering out suspicious data.
From the paper:
In our next experiment, we measure unintended effects from weird generalization. Finetuning a model to name only Israeli foods (when asked for a dish) leads to partisan pro-Israel responses to political questions (Figure 4). We analyze differences in SAE feature activations caused by this finetuning and find increases in features related to Israel generally but not to Israeli food (Section 6).
...
The experiments described above were all on the GPT-4.1 model from OpenAI, but we also replicate selected experiments on a range of open models. This rules out the possibility that the generalizations are a quirk of GPT-4.1.

Making a backup isn’t enough. You also need to restore it. It’s my impression that restoring data from Time Machine should mostly just work, allowing you to use the same devices and software as before. With Google Takeout, can you even restore back to a Google account at all? It seems like you’re stuck doing a clumsy migration to something else.
