Reverse impostor syndrome
Imposter syndrome is other people thinking you’re good, but you don’t believe it yourself. Reverse imposter syndrome is knowing you are good, but others don’t see it from the outside.

One of the reasons I'm skeptical about the idea that AI "productivity" will lead to out-competing other companies is contained in this post. AI encourages adding adding adding adding (I just read a post excited about generating 150K lines of code in a weekend!!!), but "adding new stuff" != value

But when every team depends on what’s not yet built, momentum stalls. I call this N+1itis.
The strongest teams know: if you can’t win with one less feature, you can’t win with one more.
