The most depressing part about this whole episode is how unnecessary the technology shown in it is. Sadly, we humans don't need some futuristic implant in our heads to modify our perceptions so we can kill others without remorse. The unfortunate reality is that we're more than capable of doing that already using nothing more than words... cruel, dehumanizing, hatred inspiring words. We do it to "our enemies" during times of war, we do it to scapegoats during times of internal strife, we even do it during times of plenty seemingly just because we can't help ourselves. And even long after the events that sparked the words are over the hatred lingers in our collective system, being passed on from generation to generation. It's something that has played out time and time again throughout human history and is even happening at this very moment with the Yazidis in Iraq and Rohingya in Myanmar... There are those that are even trying to make the same happen in our own backyards in the West against Muslims, Mexicans and Transgender people. All accomplished without needing any special implants, just words.

p.s. Thanks for thoroughly ruining my night and emotionally devastating me again, Black Mirror. :( Why do I keep watching you when you keep doing this to me? :P

The lack of discussion on this episode compared to others really speaks for itself.

It was IMO one of the most uninteresting and forgettable episodes of Black Mirror and had the curse of coming right after San Junipero when watching them all so I sort of was still riding the high from that episode and not getting much from this one.

I did like the concept, unlike others I didn't find it predictable at first that the roaches were people but even not knowing I was still just like 'meh' when I got that revealed to me.

Sadly it just strayed to far from the style and content that I like most about the series so it just fell flat and I completely forgot about that episode until I looked up to title to comment on it here.
