Off the top of my head, I made of list of Elmo pros and cons:
Space X- Current leader in the private space industry, but only with massive government investment (some might call that "welfare"), but continuous, repeated environmental violations. Boca Chica, Port Isabel, South Padre Island, and the southern Laguna Madre will be a giant superfund site long before Space X lands somebody on the Moon, much less Mars. Goodbye fishing, goodbye best birding in the US, goodbye best beaches in Texas. Given us a rocket that can be reused (although maybe we should wait until its successfully relaunched before we start sucking Elmo dick), looks cool on video when it lands.
Tesla- Started out well, turned to complete shit. See cyber suck, FDS, human controlled robots serving drinks (lol wut?).
Boring company- Complete joke from the start, hasn't done anything. Of course Aggy goes full aggy and hires them to bore a tunnel.... somewhere.
Neuralink- not even sure what the fuck that is, other than a money hole.
Starlink- being actively used by Russian invaders. Bringing internet to remote areas? Is it reliable, affordable, I don't know. Does it do what it was supposed to do, such as provide high speed internet to a moving vehicle? Adds to the low Earth orbit landfill (space fill?).
Twitter- lol, not going to bother.
Add in safety violations at various factories, accident rates way higher than any industry average, union busting, more ignoring of environmental regulations.
Keeps talking shit about saving humanity by colonizing mars, which is a fucking joke that a smart 9 year old knows is bullshit. If he really was concerned about humanity, he would use his fortune and alleged smarts to reverse global warming.
He's a wannabe fascist. He openly promotes conspiracy theories that undermine democracy and endangers marginalized communities. He's also a complete dipshit, horrible father to X kids from Y baby mommas, an illegal immigrant, lies lies lies, over promises and underdelivers, and is just an all around terrible person.
Extremely punchable face, wears cowboy hat backwards in an attempt to look Texan (black felt in summer in S. Texas), sports a disgusting half ass beard, smells his own farts.
Last and maybe worst (depends on your world view I guess), he's a billionaire. Billionaires should not exist in a functioning democracy. When they do occasionally show up like a turd washing up on a public beach, they should be immediately sterilized and disposed of/ taxed out of existence, and viewed as a symptom of a fucked up sewer system/ failing democracy, not something to be celebrated and idolized.
Did I miss any?
Also, sorry for bad grammar.
