Chat GPT suggests that Yoga and Rock 'n' Roll and long lasting fads. I would say Crypto is a pretty long lasting fad. But we're really splitting hair here. I agree that most people would say that something lasting decades is not a fad but everything is relative. Something, like yoga, can exists for hundredths of years but it's sudden popularity in the west can be considered a fad. My point really was that calling someone a moron because he said that 'OOP was a fad' is silly. Maybe he simply meant that it's overrated? Maybe he meant that people got way more excited about it than they should? Maybe he meant that it's popularity was dying out? You can make valid points about all of it. Saying that he's an idiot only because OOP existed for relatively long time actually shows how simple minded the other guy is.
