Musk's SpaceX IPO Narrative Is a Whole New Level of Bullshit

5 hours ago

Elon Musk has a history of making unfulfilled or delayed promises, such as autonomous driving by 2015 and a $35,000 Model 3 that was hard to buy.
His latest claim involves moving AI data centers to space to overcome Earth's power grid limitations, leveraging constant solar energy, but this ignores critical cooling challenges in a vacuum.
Cooling in space relies on thermal radiation; for example, radiating 1 megawatt of waste heat requires about 1,600 square meters of radiators, scaling to over 800,000 square meters for a gigawatt—more than 110 football fields.
The ISS sheds only 70 kilowatts with heavy, large radiators, while SpaceX plans 100 kW in a 1-ton satellite, which seems physically impossible based on current technology.
Space hardware degrades faster due to cosmic radiation, requiring frequent replacements every 2-3 years, leading to thousands of costly Starship launches annually just for maintenance.
Latency and bandwidth present additional hard physical limits that cannot be easily overcome for space-based data centers.
Musk's IPO narrative is criticized as fantasy, and if it influences valuation, it may indicate mass psychosis among investors.
