To achieve AGI, we will need to be capable of high fidelity whole brain simulations that model the brain's entire physical, chemical, and biological behavior. We won't have that kind of computational power until quantum computers are mature.
Both of those seem questionable, multiplying them together seems highly unlikely.
Even though every NES in existence is a physical system, you don't physical level simulation to create and have a playable NES system via emulation.
1) intelligence and consciousness seem to be linked and we don’t understand consciousness. It may be physical but not purely chemical and classic physics.
2) Even if it is purely chemistry and classic physics, the development process may matter. Whole brain simulation may get you a simulated lump of flesh with no electrical activity.
This is a trivial question to answer.
Maybe your point is that until we understand our own intelligence, which would be reflected in such a simulation, it would be difficult to improve upon it.
whats the next sentence i'm going to type? is not just based on the millions of sentences ive typed before and read before? even the premise of me playing devils advocate here, that's a pattern i've learned over my entire life too.
your argument also falls apart a bit when we see emergent behavior, which has definitely happened
That's what I hear when people say stuff like this anyway.
Similar to CS folks throwing around physics 'theories'
