I think this is the key point. HN commenters on this thread and related ones like to assume everybody’s an activist luddite but actually I bet the majority of the audience is just rolling their eyes at the amount of open doors being kicked in while being forced to sit still and listen to that drivel.

Which is why they booed the mention of AI specifically, surely.

It's because they're bored of the speech, not because they're angry at the hearing praise for the technology that is poised to fuck up their careers and futures

You can be pissed off about AI without being an "activist luddite" you know
