Amazon's stock price is great, sure. But I don't think their products are particularly inspired. There's a huge disconnect between how good a product is and how much money it prints. On the far end of the spectrum you have products like Oracle, SAP, IBM, etc which, despite being objectively shit, still somehow print. And then on the other side you have truly inspired stuff that is built by people who care, like (early) SpaceX, Anthropic, (early) Apple, etc. It's kind of hard (imo) to not see the difference between these two ends of the spectrum.

I think that product quality and money printing ability do eventually converge, but it can take decades to get there. The slow trickle of talent leaving the company causes the product decay over time, but there's a ton of inertia in the meantime.
