If you figure humans have general intelligence and are built out of regular matter it would seem theoretically plausible for us to build something else that has general intelligence out of regular matter. I think you may be overcomplicating things.

So you're saying that because general intelligences exist and are made of matter, we can conclude that it is possible to build a general intelligence out of metals and salts?

I don't see how that follows. Seems totally speculative to me.

If you mean possible in the "I can imagine it" sense then of course it's possible. So is a zombie apocalypse. Is it possible in the "there are models which predict it as a possibility"? Not to my knowledge.

The only such theoretical model I've seen is "processing power is increasing eventually, therefore computers will be able to do anything soon, including AGI" but that's a totally flawed model.
