Imagine 200 years ago saying the same thing. As if you have any idea the limits/bounds of anything. Especially in the face of a super intelligence, it’s absurd.
We could send a cracked team of scientists and engineers that knew everything there is to know about how to make a CPU. But you can’t build a photolithography machine when you barely have electricity or any way to sufficiently purify silicon.
Magic can just wish things into existence. Technology requires a supply chain. When it works, the latter looks like the former but they are not the same.
I don’t really want a disaster to happen to convince you that it is possible. Is there any other way?
