As the newcomer to the, very entrenched, block, I think the memristor has a lot of momentum to overcome. In a EE undergrad (2007, so it has been a bit) we spent plenty of time understanding resistors, capacitors, and inductors. We looked at example circuits and uses, we learned the math and theory... We developed intuition around them.

Memristors were the missing fourth, and "imagine what you could do with that!" My imagination did not extend very far. Everything was being built with those other three and the non-linear components.

It'll take a while to overcome that momentum.

I feel like IPv6 has a similar barrier. I'm mostly an infosec nerd and I've been through a lot of training and education. Never once seen IPv6 treated beyond, "it has more bytes, firewall it off".
