Reminds me of when we thought proteins were the be all and end all and this goopy stuff bundled up in chromosones was just some useless goop.

There's a pattern which we see again and again in nature, where incredibly complex structures and behaviours emerge from interference and feedback patterns between waves - from deciding whether your toenails grow on your face or your feet to the formation of planets, from ant colony foraging and spacing to whether it will rain on Tuesday.

I suspect elements of cognition are similar.
