I think the point, over all point is that SaaS business models are returning diminishing profits and many companies are betting the house on AI to make their businesses profitable. But what happens when the cheap/free AI these things are using gets repriced? A sudden rise in cost.

I mean, I can see the logic behind what he's writing. He's not saying AI isn't affordable for users and businesses. He's saying it is being propped up and a lot of weight is being placed on it. Weight that might collapse in a drastic weight when the true cost of these tools is revealed.

That's the subprime analogy. Tech has long been subject to these things. Venture funding is inherently risky. But a large number of SaaS businesses have bought into it.

We will see. I see value in the tools and they will and are revolutionizing tech. But we don't see the cost tradeoffs yet. That will impact their application. I think the idea of investors is that the costs can be reduced over time. But, will the funding supporting all these AIs last long enough. That's the question I have.
