Taking a look at the capabilities and deployment of AI in 2035, do I think that there was more progress than in a world without e/acc? I will resolve this entirely based on my opinion.
There are multiple ways e/acc could speed up progress - looser regulation, more funding for AI companies, more motivation to start and work in the industry, and so on.
There are multiple ways e/acc could slow down progress - political backlash, AI incidents that could have been avoided with more of a safety mindset causing strict regulation, and so on.
I'm not sure if AI doom counts as speeding up or slowing down progress. My impression is most e/accs would count that as slowing down, but the leader of the movement would count that as a success. But we won't be around to resolve the question in that case, so I don't think that matters.
