One thing to note is that you don’t know how many games humans are playing in their head in some sense. We don’t have access to that kind of information about our own algorithms. Even if you think we don’t because we don’t consciously experience/remember them, that’s obviously wrong. Every time you have a thought pop out of nowhere or an eureka! moment from the incubation effect, or every time you have a Tetris effect dream (or all the experience-replay hippocampus neuroscience), you see how it feels to have powerful subconscious algorithms churning away on difficult problems without you having any awareness of it: nothing. But they still take wallclock years to reach levels of performance that something like AlphaZero does in hours...
That’s an interesting thought. My hunch is that hippocampal replay can’t happen unconsciously because if the hippocampus broadcasts a memory at all, it broadcasts it broadly to the cortex including GNW. That’s just my current opinion, I’m not sure if there’s neuroscience consensus on that question.
Here I’m sneaking in an assumption that “activity in the GNW” = “activity that you’re conscious of”. Edge-cases include times when there’s stuff happening in the GNW, but it’s not remembered after the fact (at least, not as a first-person episodic memory). Are you “conscious” during a dream that you forget afterwards? Are you “conscious” when you’re ‘blacked out’ from drinking too much? I guess I’d say “yes” to both, but that’s a philosophy question, or maybe just terminology.
If we want more reasons that human-vs-EfficientZero comparisons are not straightforward, there’s also the obvious fact that humans benefit from transfer-learning whereas EfficientZero starts with random weights.

It’s EfficientZero, EfficientNet is an entirely different model architecture in computer vision.
Oops, thanks, just fixed it.
