We don't really know any of that for certain. We don't know what relationship LLMs and neural networks have to the actual functioning of a human brain. We don't know what relationship current computer architectures have to the architectures that allow us to create properly versatile AGIs. It could be the laptop I'm typing this on is plenty powerful. It could be you need a GPU with 100 petaflops and a few terabytes of RAM, in a similarly sized package to this laptop because the speed of light is too slow when you're working across GPU arrays.
