I always enjoy reading analysis/ideas/intuitions about how the brain works, because it provides inspiration for machine learning improvements that can be applied in the real world.
That said, I’m still optimistically waiting for Numenta (and Geoff Hinton’s capsule theory) to set the new bar at one of the many difficult image/speech/language/etc recognition challenges.
Ideas are great, but at the end of the day science moves forward when we measure our ideas against reality. (To the credit of this paper, it does make a series of predictions, though those seem extremely difficult to measure in biological systems for the time being.)
