Because he's the main character, the bestest boy, the very smartest, and his mommy even tweeted so just before he did that jump.

Even Trump knows he's cringe

The theory I subscribe to is he got addicted to internet clout by being offbeat and le random xD with tweens after his PewDiePie appearance.

He was content with cameos on The Big Bang Theory or Iron Man as the South African Thomas Edison (in more ways than one). Someone online redditors and tech bros know as some eccentric rocket/car maker.

But after PewDiePie, he tasted the approval of mainstream children. He was on stage with a modern celebrity tasting modern fandom. He's chased that high ever since. And the more he's chased it the more insufferable he's become to a regular person.

All that's left are people too braindead to see through his PR, who think he's an actual Tony Stark genius, and those same braindead morons are overwhelmingly right wing because once again they're too dumb to not fall for right wing talking points. And of course he's pandering to them, the only people who still like him, because affection is the only thing he can't buy.

Emerald mine money can buy him cars, a PR team, a "founder" title, degrees and a reputation as an epic inventor. But it cannot buy him affection. Not from his children, not from people with an ounce of common sense.
