I can't read the full story because of the paywall so I can't be sure of the point.

From the title it sounds as good as if we need bigger legs to keep up with cars. However there are fundamental differences between moving around and thinking. I'd be surprised to be able to get a bigger brain in time to be on par with AIs. I'd be more surprised to have the time or the will to go through all the training that would make me an expert in several fields. However we already have specialized AIs in many fields. An example: I played a few thousands of games of Go, a typical pro played tens of thousands, AlphaGo millions. It had nothing else to do. I'll never match that, even with a bigger brain.
