You need exaflops, the equivalent of a million Nvidia GPUs. And the brain has to use less than a thousand watts. Even if you go full analog and hardwire with the current architectures, you will not succeed. Massive trimming, low precision, and probably forward forward instead of backprop is required. But that will likely only produce dumb robots with static microbrains.

It's much easier to train chimpanzees. Or create chimp cyborgs. Realistic spiking neural networks with neuromorphic hardware could get us robots, but it will take decades.
