You’re right that many .com companies lacked fundamentals but you’re cherry-picking survivors. For every Amazon, there were dozens of Pets.coms. The current AI wave does feel different in terms of revenue traction (e.g., Cursor’s $500M ARR), but the broader lesson still applies: hype cycles don’t discriminate between good and bad execution in the short term.

Cursor’s growth is impressive, but sustained dominance isn’t guaranteed. Distribution, margins, and defensibility still matter and we haven’t seen how durable any of that is once incentives tighten and infra costs stop being subsidized.
