I mean I hate Musk as much as the next Musk hater, but I can understand why SpaceX IPO'd and why OpenAI would hide their audit and finances.
SpaceX literally made self-landing rockets. They're not a Tesla or a Boring Company bullshit scam. They did something that was amazing, and still is, and opened the door to much cheaper launches into orbit, meaning they can get so many government contracts for anything they need to do in space.
It is WAY cheaper to put stuff in orbit now thanks to SpaceX. That's why they also went for low earth orbit internet and did starlink. Their own tech made starlink possible. Now I'd never use starlink because fuck Musk, but this is a direct result of SpaceX doing groundbreaking work.
Literally everything Musk does rides on the popularity of SpaceX actually making a massive achievement in rocketry. Tesla fucking sucks and doesn't even make the best self driving electric vehicles. The Boring company was a failure and/or scam. Starlink is a fucked up attempt to get everyone's data... Which would be a cooler idea if it weren't related to Musk but I need to have a tiny bit of trust in my ISP, sorry.
Only SpaceX ever did something cool, and it was legitimately really cool, and the result of good engineers doing work that Musk took the credit for.
