Last time something genetics based was developed fast, and succesful, quite a few people went on the fences over it: Covid mRNA vaccines.

There are reasons why medical development takes time and money. And why rare diseases are underserved. And no amount of "disruption" is going to change the simple question of cost in that equation. So if VCs want to change that, they can simply use some of their "free" billions to fund proper development and research.
