Jesse Peltan@JessePeltan· Mar 22, 2026A 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.

Elon Musk@elonmusk· Mar 21, 2026Formal announcement of the TERAFAB project, which will be done jointly by @SpaceX and @Tesla, tonight around 8pm CT. Livestream on 𝕏.
The goal is to produce over a TERAWATT of compute per year (logic, memory & packaging) with ~80% for space and ~20% for the ground.

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

The largest data center in the world is planned to be built in Ohio, and it'll cost up to $40,000,000,000 to construct.
The 3,700 acre center will require 10 Gigawatts, 1/3 of Ohio's entire power grid capacity, to run.

Lots of “impossible” things suddenly seem inevitable when costs come down by a few orders of magnitude.
This happened with batteries, and people still haven’t realized it.
X Freeze@XFreeze· Mar 21, 2026It’s actually insane what SpaceX is doing to the space industry right now
In 1981, it cost ~$65,000 to put 1 kg into orbit
For 50 years, the industry accepted this as the standard. Reusable rockets were "impossible"
Then one company - led by a man obsessed with getting humanity

We do indeed need to chimp about this. Debanking illegals is the kind of tactic that can actually work at scale. ICE agents cannot manually round up every illegal. We need to induce self-deportations. Trump needs to tell the banks to stuff it and issue the order.
