It doesn’t matter how smart it is. 200 years of technology were not accomplished by thinking harder. It required empirical observation, new materials and tools, and supply chains.
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 think some people are just immune to understanding the implications of super intelligence. Like a severe lack of imagination, they only believe something once they see it and afterward claim it was, ‘obvious all along’.
I don’t really want a disaster to happen to convince you that it is possible. Is there any other way?
