It is very unlikely that a new genius developer, would know how to navigate the political landscape.

They would probably come in and redo everything from scratch -- everyone would tell them to get lost, and they would. This is what happened to Vitalik for example https://bitcointalk.org/index.php?topic=431513.0 even though he was a longtime writer for Bitcoin Magazine.

I am not a believer in Vitalik's idea -- but no one serious tried to help him implement it on Bitcoin. So it is with many Bitcoin ideas.

Building on Bitcoin, or even getting new Bitcoin merchant adoption, has fallen out of favor.

You will get support if you "build on lightning" but that is frankly part of the problem -- it reduces creativity by funneling people all into one narrow sub-field of Bitcoin.

It isn't True Creativity unless your invention will put dozens of other people out of a job.
