For all its innovation, computers are largely still modeled around the fundamental model defined by Neumann Janòs (or John von Neumann, depending on your preference) in the ’40s: CPU connected to memory through a bus. You can make the system faster by making faster each element, but the complete system will never be faster than the slowest link in the chain.

Our brain seems to be wired differently: CPUs and memory are much slower, but they are massively parallel-connected.
