Ever notice how cycles repeat? A legendary contrarian investor is sounding the alarm on the current AI sector, drawing parallels to past market euphoria. He points to a famous billionaire's earlier retail investment blunder as a cautionary tale—when exuberance clouded judgment. The takeaway? Markets get ahead of themselves. Just because everyone's betting on something doesn't mean the fundamentals are solid. Whether it's tech stocks or digital assets, the pattern's eerily similar. History doesn't repeat, but it sure does rhyme. Keep your eyes open and your positions sized accordingly.
