[Classic] General Mario speedruns involving glitches or tools of some kind

What's the point of speed running a game if your'e cheating ?
I mean, sure it's cool to post something like thet on youtube , I understand thet.
but using cheats in videogames before beating the game without cheats seems stupid.
Here's a super mario 2 speed run i found.

And then you have stuff like this guy that beat Mega Man X and X2 simultaneously (i.e., with the same set of controller inputs):
TASVideos movies: #380

Or these dudes that did the same with four Mega Man games at once:
TASVideos movies: #871

Oh wow, thet's incredible.
I lack the attention span to beat one of them so fast too!
I remember seeing a video where a guy is beating super mario n64 in about 20 minutes ,I don't remember it too much but I think he was using cheats.
Ill try serching for thet video.

There's nowhere I can't reach.
