Why graphene hasn’t taken over the world...yet https://www.youtube.com/watch?v=IesIsKMjB4Y

Ugh I hate it when they say "A sheet of graphene could support X". It's utter bullshit because you can't ever have a sheet of defect-free graphene.

It's like how defect-free glass is 2-4 times stronger than steel. Actual glass is obviously nowhere near that strong and nobody pretends it is.
