A bunch of people create the most OP way of travelling and barely use it, and don’t tell me that the ship is unique and Stamets is the only person in the universe in the following centuries to be able to use it, because that just doesn’t make any sense, it’s a cheap trick to justify why such an incredible technology has never been mentioned after, not even by a super villain that gives no crap about genetic augmentation.

That wasn’t really the reason, the reason wasn’t nobody else could figure it out or that nobody wanted to do it because it required genetic modification, the reason was that jumping on the mycelial network was actively killing it unless I am misremembering things which is in line with the rest of star trek’s ethos (how about the DS9 episode where they help the dominion destroy a trans warp gate for example? There are other technologies that are abandoned and hidden for the greater safety of the universe all over Star Trek, it can be really silly I agree but I don’t think discovery is unique here.
