What's the deal with the Temp folder?

A buddy of mine keeps telling me it’s actually good for my machine to occasionally clear out everything inside the Temp folder on macOS.
Does anyone actually know what you gain from doing that, or if it even does anything at all?

This guy thinks he’s some kind of genius because he knows how to execute a command without having the slightest clue why he's doing it... He's just talking nonsense. He probably only left a few gigs for his system drive, so now he's panicking over space and deleting everything in sight just to feel productive...

Just leave it alone. We're talking about such a tiny amount of space that it honestly doesn't matter. And don't you think there would be some documentation out there if this was actually something worth messing with...

Tell him he'd actually free up a lot more room if he just cleared out his Temp folder... 👍

Alright, listen up, folks
Thanks

Feel free to tell your colleague he's being a bit dense. That Temp folder is actually there to boost performance.
It works by caching data about the files and apps you run most often, so the next time you boot up your Mac, everything feels a little snappier and more responsive...

There’s really no reason to go around deleting things in there; the system manages itself. Did I mention you should probably tell him he's being a bit dim?

Gotcha
Thanks
