Yes, well, remember the dot-com boom/bust cycle? Lots of people lost a lot of money then but not all of those stocks ended up becoming worthless. Some held on to what they had and made a fortune once the internet-hype was over and the internet-era began. The same could happen with some - but certainly not all - of these 'AI-exposed' stocks. Once the 'AI' hype is over the 'AI era' will probably begin, especially if the dearth of RAM and matrix processing capacity is solved somehow.
