To be honest these search results being months apart shows quite the opposite of what you're saying...

Even though I agree with your general point.

This is literally a discussion on allocation of capital, it's not a reach to say that capitalism might be involved.

Right, so you draw a line from that to abolishing capitalism.

Is that the only solution here? We need to destroy billions of lives so that we can potentially prevent "unsafe" super intelligence?

Let me guess, your cure for cancer involves abolishing humanity?

Should we abolish governments when some random government goes bad?

"Abolish" is hyperbole.

Insufficiently regulated capitalism fails to account for negative externalities. Much like a Paperclip Maximising AI.

One could even go as far as saying AGI alignment and economic resource allocation are isomorphic problems.

Agreed. At the same time, regulators too need regulation.

From history, governments have done more physical harm (genocides, etc) than capitalist companies with advanced tech (I know Chiquita and Dow exist).

It is a trendy but dumbass tautology used by intellectually lazy people who think they are smart. Society is based upon capitalism therefore everything bad is the fault of capitalism.
