Couldn't agree more! The ones that are found out often have network that pushed their product or build. Plenty of silent builders make amazing apps, tools. Every once in a while you stumble upon think of packages libraries on npm, pip. Langchain is one example of how it took off.
Most are perfectly fine building stuff without being found out. That's not the fun part of why people build things.
Although there is satisfaction in knowing something you built getting used.
