From my experience with 3D rendering, I’d say the visual fidelity of the worldmodel sitting in my sensorium at any given moment of walking around an open environment would take something on the order of ~200x250W GPUs to render, so that’s 50KW just for that. And that’s probably a low estimate.
Then consider that my brain is doing a large number of other things, like running various internal mathematical, relational, and language models that I can’t even begin to imagine analogous power consumption for. So, let’s just say at least 200KW to replicate a human brain in current silicon as just a guess.

(The visual fidelity is a very small fraction of what we actually think it is—the brain lies to us about how much we perceive.)
