The world would pretty much immediately grind to a halt because, surprisingly enough, i don't know everything.
Power stations would shut down, water treatment plants would fail, crops would fail to get harvested, air traffic would be a disaster, etc. I will say that once i figured out that it all relied on "me" i would put in serious effort but it couldnt possibly make up for the lack of knowledge.
On the plus side conflicts would likely just end because I'm mostly a pacifist and open minded.
It would temporarily be pretty chill.
Ya boi (that's me) is known among friends to be easy-going, relaxed, and easy to work with.
...Until it devolved into chaos and we all died, anyway.
Edit: oh and obviously Lemmy would die :(
I could probably figure out how to keep it running with all the information online but with everything else going on...
