Videos Like This Make Me Want to Quit Chess

The guy there is an IM. He is obviously excellent at long OTB chess. This is how he improved his chess. He is playing like a sub 1200 player in that video. If you notice he is premoving the opening basics and calculating jack shit. In the middle games he is half premoving the likely moves using his intuition half the time and the other half looking for cheapos. Though I admit he is skilled at premoving using his intuition and anticipating quick due to his experience at this half bullet nonsence.

It's a progression...
Crawl, walk, jog, and only then run.
Don't be discouraged. No one begins by running.

Absolutely impressive, but while I could spend hours watching GM's play 30/0 games for hours, while enjoying the commentary, this type of game bores me after watching more than five minutes.

Question:
How much original thinking do you think people utilize in those super fasdt games? And how much of it is memorization?
I just can't see how a human benig can think that fast and still play well. It takes me FOREVER to read the board and make a decent move.
Yet, these super stars can just play awesome moves in 1 second or less? I mean if they're processing things that fast and that accurately and brilliantly, then there's no hope for us mortals that take 5+ minutes for moves.
I mean we're literally talking 1 second or LESS for these moves. Does the brain even think during that 1 second?

Do these guys think when they play that fast?
How can people get so good and play that fast? And how do they SEE everything that fast?
I have to look at stuff slowly and probably miss over 50% of the stuff good players see.
Is board vision and chess thinking/skills like these just innate?
