The Cheapest Place to Put AI Will Be Space
Space-based solar power provides five times the energy density of ground-based panels because there are no atmospheric losses or day-night cycles. As terrestrial grids hit a bottleneck, orbital data centers will rapidly become the only viable option.
The Three-Company Casting Monopoly
You can get turbine parts quickly except for the specialized blades and veins, which are cast by only three companies worldwide. This massive backlog is forcing Tesla and SpaceX to consider manufacturing these high-precision parts in-house.
Hundreds of gigawatts in 5 years
The orbital launch of AI compute is expected to reach several hundred gigawatts per year within a half-decade.
20 to 30 ships for 10K launches
This flight cadence is fully aligned with SpaceX's long-term plan to scale toward 10,000 to 30,000 launches a year.
5-year timeline for semiconductor volume
The multi-year timeline creates an structural bottleneck that makes chips the ultimate constraint once energy is unlocked.
2026 power bottleneck limit
This power generation deficit will lead to massive backlogs where physical chips pile up unused in warehouses.
Manufacturing Satellites on the Moon
Since lunar soil is roughly 20% silicon, we can extract raw materials on the moon to produce solar cells and aluminum radiators. Sending lightweight logic chips from Earth and launching the finished satellites via a lunar mass driver is the only way to scale past the petawatt level.

Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Maximizers earn more but are less happy than satisficers

People regret inaction more than action long-term
Research consistently shows that while people may initially regret poor decisions, in the long run they regret the decisions they didn't make — inaction — far more than the ones they took.
