I've read somewhere that even some janitors / lunch ladies became millionaires from their shares. Looking then at the great performance of some other stocks, I really wonder where we're headed
I would be surprised if janitors get shares. This is Musk we’re talking about.

Scott Manley has a great video breaking down the physics and it absolutely works: https://m.youtube.com/watch?v=FlQYU3m1e80
I am a mechanical engineer, I have a multi decade career doing exactly these kinds of thermal analysis. This video is basically saying that cooking data centers in space is possible. It is. The question is if it's better, in any way, to putting them on earth. It isn't. The common misconception I see is that people think that space is cold like Antarctica is cold. It isn't. Antarctica is cold because there is lots of…
Instead of just stating “it won’t work” why don’t you actually do the calculation yourself and show why it won’t work?
Yes they have an incentive to put things in space, but it actually is a decent idea if they can execute on it the same way they did with Starlink. There’s huge demand for compute, many data center projects on earth are being scuttled because of NIMBYs and lack of power, there are no NIMBYs in space and a sun synchronous orbit means you can power them without batteries.

You obviously didn’t watch the video, he literally does the heat transfer math using radiation only, it works just fine.

This talk will help put it in perspective: https://californiaconsultants.org/event/energy-and-thermal-m...
In order to talk about these things we need to think about the power from the grid, all the way to the cooling water coming out. Not just talk about how we can calculate or optimize each little piece. Of course we can do that, it's the overall system we are talking about and need to understand.
Forest for the trees.
What do I mean by that here?
He does the calculations for 20 kW. Which sounds like a lot. It's only enough to cool one node, not one rack, one node, in a modern data center. The starlink satellite he referenced is viewed as the absolute most modern thermal design in a satellite.
Most data centers have 2000-5000 nodes and the hyperscalers have 100,000 or more.
So to replace a single data center we need 2000-5000 of these things up there, at a minimum, or one thing that is 2000-5000 times bigger.
And maintenance.
And the hardware gets obsoleted every few years.
Or you could just put it in the desert in Nevada. But we don't need rockets to get there.

Something like ~500 new millionaires is what i've read on x.
the level of cynicism being communicated on this thread is astounding!

It'll end in suicide or OD. Every time he pulls off a coup like forcing huge indices to buy and hold massive amounts of $80 billion float he delays the inevitable but in the end his puffery will collapse at some point. I feel second hand embarrassment for all the bankers and analysts who have felt the need to pump this
I think he's steadily working towards "too big too fail": make the entire US economy depend on his rat's nest of a megacorp, plus miltech/policetech (SpaceX, Grok).

This quote refers to shorting; it's not applicable to every bear position anyone ever attempts to take. You won't go insolvent buying puts.
You won’t go insolvent but you’ll consistently lose money every time the stock doesn’t go down.

Yep, and if you buy stocks you'll consistently lose money when the stock doesn't go up.
