Do you think you could build craigslist? Why are they worth so much?

I think that's comparing something different. I've seen the one-day vibe code UI tool things which are neat, but it feels like people miss the part that: if it's that easy now, it's not as valuable as it was in the past.

If you can sell it in the meantime, go for it and good for you, but it doesn't feel like that business model will stay around if anyone can prompt it themselves.
