The brain is analog and chemical, AI will be digital and silicon. We have no idea how the map from one to the other.

Says who?

Sure, if you assume that “AGI is just scaling up GPT”, it will be digital and silicon. But that’s a big assumption.

For all we know, AGI will only ever, if it exists, be analog and chemical.

Plus, even if we had an easy one-to-one mapping function between them, we don’t understand the source well enough to do the mapping.

It does not need to be, but today the computers we use are overwhelmingly based on silicon. Also OP mentioned AI, not AGI.

An analog-to-digital and digital-to-analog converter is less than a cup of coffee in some places [1].

Oh god so my background is CE/ECE stuff and you managed to trigger me. I don't want to be rude... just bluntly saying you triggered me. Doing something really small for A/D D/A with 8bit and not worrying much about resolution and data loss is one thing. For something massive scale the problem is a lot less trivial and a lot more mathematical.

Is the Quantum computer hypothesis dead?

[Filligree]

I don't see how quantum computers are relevant? We can't build them, and there certainly isn't any interesting quantum computation in the brain.
