Ugh, Elon Musk attacks British diver who called his submarine 'just a PR stunt'

After Vern Unsworth, a British diver who helped rescue the trapped Thai soccer team, called Elon Musk's attempt at a submarine rescue "just a PR stunt" that had 'absolutely no chance of working," Musk has chosen to be angry online. 

Surprise!

In a series of tweets Sunday morning, Musk referred to Unsworth as a "pedo," requested video of the cave rescue, retracted that request, then promised proof that his submarine could have, in fact, performed the rescue.

It's a lot.
