I think many haven't heard of or know the DDD+CQRS terminology.

I even suspect if Peter Hunt mentioned how they are doing DDD+CQRS for building applications, it might have been met with ridicule from audience.

It is kind of interesting, the field of software engineering is not that old, but there already probably multiple cycles of the same concept being rediscovered over and over again.

Another rather cliche one is callback based concurrency. There was a wave of "oh look at this new thing we discovered, you don't block and instead provide a function to be called later". And many older folks probably looked at each other and said "Wait, what year is it?"
