For me, that moment was cryptocurrency. "Vastly overhyped, driven by pure greed and speculative narratives, limited implementation and high energy cost." - all applied. I couldn't understand why so many people thought it was the future. I actually see LLMs a little more positively - mildly interesting, certainly intriguing language mimics, but enormously expensive and overhyped. Are they useful? Maybe, but not to the degree that everything is focused on them now.
