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.
To your second point, we have little to no ability to understand yet what quantum effects may or may not be active in brain/consciousness function. We certainly can’t exclude the possibility.
I mean lots of people have tried to build quantum computers, and so far no-one has succeeded in anything that's describable as a "computer", instead of "half a dozen logic gates". Perhaps in the future.
We can fairly well exclude the possibility of interesting quantum effects in human consciousness, because the human brain is a hot, dense environment that might as well have been literally designed to eliminate the possibility. It's the exact opposite of how you want a quantum computer to be built.
Which doesn't mean there aren't plenty of quantum effects involved in the molecular physics, but that isn't what is normally meant by 'quantum computer'. Transistors would also meet that definition.
1) That 433 qubits does not make a computer and is instead “a half dozen logic gates.” I agree a half dozen logic gates is not a computer. 433 qubits is not comparable in terms of information capacity or processing capacity to a half dozen logic gates. This number is also publicly doubling annually now — I would bet the systems we don’t know about are more complex. Importantly, a computer in this context is not something you would attach a monitor to — it is just an electronic device for storing and processing data.
2) That we have any good idea of the limits of how biological systems might be influenced by quantum effects within specific temperature ranges. You certainly wouldn’t construct a human brain to interface with quantum effects given the present state of our knowledge in constructing these kinds of systems. But then we can’t even construct a self-replicating cell yet, nevermind a brain. It’s hard to imagine we understand the limits at work there.
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.
> We have no idea how the map from one to the other.
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.
