What you make of this memo really depends on who you are and how you're positioned. The dot-com era was absolutely a bubble. Tons of companies died, but the internet itself didn't go away, and the people who backed the right companies did extremely well. The 2007 housing bubble, on the other hand, was a totally different kind of event: broad, systemic, long lasting, and painful for almost everyone.

AI looks a lot more like the former. Some companies will fail, valuations will swing, but the underlying technology isn't going anywhere. In fact, many of the AI firms that will end up mattering are probably still undervalued because we're early in what will likely be another decade long technology expansion.

If you're managing a portfolio that needs quick returns and can't tolerate a correction, then sure, it probably feels like a bubble, because at some point people will take profits and the market will reset.

But if you're an entrepreneur or a long-term builder, that framing is almost irrelevant. This is where the next wave of value gets created. It's never smooth and it's never easy, but the long-term opportunity is enormous.
