I mean he single handedly pulled the future forward in two different industries so far. Just because he is not "well adjusted" on twitter doesn't mean he cannot get shit done.
This is the single bizarrest and most literally inaccurate use of the phrase “single-handedly” I have ever seen.
What Tesla and SpaceX have done are enormous human undertakings. He did not single-handedly do it by any rational interpretation. The delusional self-confidence he used to get investors to pay for those undertakings is what's about to destroy Twitter.
