Did you even think about this comparison before you typed it?

Musk's pre-Twitter and unexagerated legacy is luxury cars and some vague stuff about space.

MLK Jr is a human rights icon who was assassinated.

Musk is still eligible for his legacy holding a science victory. For example if he can get something more substantial to happen on the moon/mars or kick start asteroid mining.

Right now his legacy is proving billionaires aren't geniuses and that meritocracy is a lie.
