My least favorite part of my own personal experiences on masto would have to be that any time I mention quantum computing, I get folks explaining it to me.
There's exceptionally few people on the planet who know more about QC than me, on the order of 100 or so, given my 20 years doing that shit, and having outright invented significant parts of it.
When I say that QC probably shouldn't be part of your personal threat model, I mean it.
