Whenever space data centers become cost effective, they'll get there first for the company that is vertically integrated with the software, the computer hardware and the launch capabilities. Terafab is news, but it's not a surprise to anyone that's been paying attention.

A terawatt *per year* is HUGE on the scale of current civilization (2x the U.S. grid every year), and yet that’s still 100,000 years to reach Type I, and 10^14 years to reach Type II. This is still only the beginning.

If the average chip is 1 kW, this would be 1 billion chips a year. Assuming this is about five years away, at that point Tesla will hopefully be making 100 units of Optimus a year and 20 million cybercabs a year, for a total of 140 million chips. That means over 800 million
