> The basic math is that launching a million tons per year of satellites generating 100 kW of compute power per ton would add 100 gigawatts of AI compute capacity annually, with no ongoing operational or maintenance needs. Ultimately, there is a path to launching 1 TW/year from Earth.

> My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space.

This is so obviously false. For one thing, in what fantasy world would the ongoing operational and maintenance needs be 0?

Currently, just a cursory google search shows $1500-3000 per kilogram to put something into low earth orbit. Lets take the low bound because of efficiencies of scale. So $1500.

A million tons will cost $1500x1000x1000000= 1,500,000,000,000. That is one and a half TRILLION dollars per year. That is only the lift costs, it does not take into account the cost of manufacturing the actual space data centers. Who is going to pay this?

That launch cost is remarkably cheap to someone that's handled a $1.5million dollar 5U server filled with GPUs and RAM that weighs under 100kg.

Obviously the solar and cooling for the above would both weigh and cost a ton but... It's feels surprisingly close to being within an order of magnitude of current costs when you ballpark it?

Like i don't think it's actually viable, it's just a little shocking that the idea isn't as far out of line as i expected.
