"Couple years ago everything was built on a blockchain" I've never worked anywhere where blockchain was used. "years before everything was going microservices" The vast majority of software architecture has gone microservices. "earlier everything was moving to the cloud" I've worked many places where the cloud was used but never 100%. You are right, blockchain was a fad, everything else you cited are valid and remain.
