The narrowing gap between human and animal intelligence

Intelligence seems simpler than we thought, just a matter of scaling things up, so human intelligence is more likely a difference in degree rather than a difference in kind/step change. Plus this suggests there’s a wider range of possible intelligences out there, so in the grand scheme, human and animal intelligence will look very similar/closely related (it looked less that way when they were the only games in town. Then they were as far apart as was known to be possible).
