Building on Elon Musk's February vision of Optimus as the first Von Neumann machine and his recent March 21 statement that Optimus+PV will be the first self-replicating probe in space, Tesla announced Terafab on March 22 as the next step toward becoming a galactic civilization.
Elon Musk posted on X on March 21, 2026: 'Optimus+PV will be the first Von Neumann probe, a machine fully capable of replicating itself using raw materials found in space.' This advances his earlier February comments positioning Tesla's Optimus humanoid robot as the pioneer Von Neumann machine—a self-replicating system theorized by mathematician John von Neumann for autonomous space exploration and construction.
The next day, March 22, Tesla announced: 'Announcing Terafab: the next step towards becoming a galactic civilization,' with a live broadcast at https://twitter.com/i/broadcasts/1yKAPMzlvgWxb.
Optimus+PV likely integrates Tesla's humanoid robot with photovoltaic or advanced power systems for space operations. Terafab appears central to this trajectory, though details remain undisclosed. These announcements underscore Tesla's ambitions blending robotics, AI, and space technology for interstellar expansion.
