Two thoughts: The best startups are masters of asymmetric warfare -- they don't fight on the battlefield the incumbent selects. And, users often understand their problems well but are horrible at suggesting features to solve these problems.
chatgpt has no social features or built-in sharing, you have to sign up before you can use it, no inherent viral loop, etc.
seriously questioning the years of advice i gave to startups 🙃
If 0 to 1 is about product-market fit, -1 to 0 is about founder-market fit. Figure out what you want to build and why you are the right person to build it before you start.
