TAS put speedrunners to shame...
....not at all, they actually make RTA (real time attack) progress a lot.
See, RTA and TAS often teams up together because the philosophy is not the same and can potentially help the RTA community. I personally lived and heard that.
See, TAS has their philosophy to search and investigate heavily on the ins and outs of the game (essentially similar to gltich hunting) to give the theoretical best possible outcome that can ever exist. RTA has their philosophy to try to give the most consistent strat that any human can perform with some practice and learning.
What happens is gltich are often discovered by tasers that are humanly possible. I lived this with TTYD and I heard many stories. RTA can also helps tasers because RTA people are trained to do VERY repetitive tasks, they can give better idea on what feels faster which can help TAS that has to go through one run with tons of savestates and only repeat stuff like RNG. Btw, RTA can give better statistics on RNG which can help TAS to figure the RNG oput and manipulate it.
You will never see TAS and RTA separate, they just are different are are very closely related. RTA wouldn't be that awesome without TAS and same for the opposite, it;s a very close relation.
This is why both side exists
