No, rockets landing themselves is just controlling the mechanism you use to have them take off, and builds on trust vectoring technology from 1970s jet fighters based on sound physics.
Figuring out how to radiate a lot of waste heat into a vacuum is fighting physics. Ordinarily we use a void on earth as a very effective _insulator_ to keep our hot drinks hot.
This is a classic case of listing all the problems but none of the benefits. If you had horses and someone told you they had a Tesla, you'd be complaining that a Tesla requires you to dig minerals where a horse can just be born!
It's a matter of deploying it for cheaper or with fewer downsides than what can be done on earth. Launching things to space is expensive even with reusable rockets, and a single server blade would need a lot of accompanying tech to power it, cool it, and connect to other satellites and earth.
Right now only upsides an expensive satellite acting as a server node would be physical security and avoiding various local environmental laws and effects
You need to understand more of basic physics and thermodynamics. Fighting thermodynamics is a losing race by every measure of what we understand of the physical world.
From what I understand, very, very large radiators every few racks. Almost as much solar panels every few racks. Radiation shielding to avoid transient errors or damage to the hardware. Then some form of propulsion for orbital corrections, I suppose. Then hauling all of this stuff to space (on a high orbit, otherwise they'd be in shade at night), where no maintenance whatsoever is possible. Then watching your hardware progressively fail and/or become obsolete every few years and having to rebuild everything from scratch again.
The difference is that it was mostly clueless people like Thunderf00t who said it was impossible, who nobody took seriously. I don’t remember that basically all relevant experts claimed it was near impossible with current technology. That’s the situation now.
There’s also fairly clear distinction with how insane Elons plan has become since the first plans he laid for Tesla and SpaceX and the plans he has now. He has clearly become a megalomaniac.
Funnily enough, some of the things people said about Tesla is coming true, because Elon simply got bored of making cars. It’s now plausible that Tesla may die as a car company which I would not have imagined a few years ago. They’re arguably not even winning the self driving and robotics race.
No, people made fun of Elon for years because he kept attempting it unsafely, skirting regulations and rules, and failing repeatedly in very public ways.
The idea itself was proven by NASA with the DC-X but the project was canceled due to funding. Now instead of having NASA run it we SpaceX pay more than we'd ever have paid NASA for the same thing.
SpaceX is heavily subsidized and has extremely lucrative contracts with the US government. Not to mention they get to rely on the public research NASA produces.
He also said he could save the us a trillion dollars per year with DOGE, and basically just caused a lot data exfiltration and killed hundreds of thousands of people, without saving any money at all
Currently SpaceX have managed to land the booster only, not the rocket itself, if you are thinking about Starship. And reusability of said rocket is also missing (collecting blown up pieces from the bottom of the ocean doesn't count!).
