I Become disappointed After This Video !

Hello Everybody i'm still a beginner in chess and when i've watched this video i really become disappointed and thinked to quit chess for ever ! :(
here it is :-
https://www.youtube.com/watch?v=KwT1zyfy438&

it's between Magnus Carlsen And someone i dont know 

Why? It's just a live very fast almost bullet speed chess game between Magnus and Laurent Fressinet, which people may recognize because of Magnus comments. "Too weak. Too slow."

It looks like they are having fun, doesn't it? 

i thought chess is a mind game which you have to think deep before you play and so i was doing, I was thinking for about 5~8 minutes before i play and when i watch these guys playing each game in femtoseconds i really become disappointed because they play chess as "1+2=3" ,They Dont Think At All !!

I don't think there is anything wrong with them having a little fun.

I only play chess for fun. Let those two have fun too!
