Yeah, you should talk to someone who knows more about security than myself, but as a couple starting points;
math-proven safe AIs
This is not a thing, and likely cannot he a thing. You can't prove an AI system isn't malign, and work that sounds like it says this is actually doing something very different.
You can do everything you do now, even buy or rent GPUs, all of them just will be cloud math-proven safe GPUs
You can't know that a given matrix multiplication won't be for an AI system. It's the same operation, so if you can buy or rent GPU time, how would it know what you are doing?
This would benefit greatly from more in-depth technical discussion with people familiar with the technical, regulatory, and economic issues involved. It talks about a number of things that aren't actually viable as described, and makes a number of assertions that are implausible or false.
That said, I think it's directionally correct about a lot of things.
Strong +1 to the extra layer of scrutiny, but at the same time, there are reasons that the privileged people are at the top in most places, having to do with the actual benefits they have and bring to the table. This is unfair and a bad thing for society, but also a fact to deal with.
If we wanted to try to address the unfairness and disparity, that seems wonderful, but simply recruiting people from less privileged groups doesn't accomplish what is needed. Some obvious additional parts of the puzzle include needing to provide actual financial security to the less privileged people, helping them build networks outside of EA with influential people, and coaching and feedback.
Those all seem great, but I'm uncertain it's a reasonable use of the community's limited financial resources - and we should nonetheless acknowledge this as a serious problem.
You very much do not know what you are talking about, as that linked "explanation" makes clear.
I'm not sure if you're honestly confused, or intentionally wasting peoples time, but either way, you should spend an hour or two asking 4o to explain in detail why an expert in AI would object to this, and think about the answers.
