not sure about "never existed" but mostly forgotten
Memristor was invented (proved mathematically) in 1971. Surprise, surprise! :) Really, some materials that have such properties (changing resistance propertiy after passing some charge through) was known earlier, but nobody cared to study them.
started to be used recently: memristors
Just like that fuel cells, advanced supercapacitors, quantum computers, fusion reactor and so on. Next year wie definitely will have them in production. And that lasts for decades.
Not if those technology serves them.
What fundamentally new tech never existed before was developed since 1970?
