If unfettered access to AI has good odds to just kill us all, we'd want to restrict it. You'd agree I'm sure, except your position is implicitly that AI isn't as dangerous as some others make it out to be. That's where you are disagreeing.
Now, if 80-90% of devs and startups are gonna be wiped in this context, the same applies to those one in the middle, accountants, data analysts, business analysts, lawyers. Now they can eat the entire cake without sharing it with the human beings who contributed over the years.
I can see the regulations coming, if the layoffs start happening fast enough and households income start to deteriorate. Why? probably because this time is gonna impact every single human being you know, and it is better to keep people employed and with a purpose in life than having to tax the shit out of these companies in order to give back the margin of profit that had some mechanism of incentives and effort in the first place.
This is not a very charitable assessment of the adaptability of devs and startups, nevermind that of humans in general. We've been adapting to technological change for centuries. What reason do you have to believe this time will be any different?
chemical and biological weapons / human cloning / export restriction / trade embargoes / nuclear rockets / phage therapy / personal nuclear power
I mean.. the list goes on forever, but my point is that humanity pretty routinely reduces research efforts in specific areas.
