Dave Nadig from VistaShares says we're in the second or third inning of the A.I. game, and it will move "slower than a lot of people will expect." He urges people to invest in names that aren't as big and flashy as Nvidia (NVDA), noting there's a lot more to the A.I. with data centers, cooling mechanics and infrastructure buildout. He highlights how VistaShares' Artificial Intelligence Supercycle ETF (AIS) offers that broader exposure.
