I can't speak to the US, but in my time in Ontario high schools and universities since 2021, there has been 1-2 HEPA air purifiers running in every classroom and lecture hall. That's different from business use, but I just spend my time in educational settings.

Yeah, I've used it for #1 for weirdly specific emails. I work with young kids, and I keep a pretty upbeat tone in my emails to parents. ChatGPT has helped bridge the gap between the tone I imagine and the content I need w/o wasting 20 minutes on one sentence.

A rule with loopholes & exceptions and inconsistent moderation causes way more frustration to artists and everyone. Yes, filtering the human experience may be wrong on some level, but people want to be able to scroll on social media around their kids, colleagues, and randos on transit.

I think it's mostly about enforceable content policies: obviously there's a line between nudity in old fine art vs a sex worker in an explicit pose, and it's great that bsky has distinct filtering levels for this! But drawing the line between furry art w big boobs and fine art w boobs is harder.
