Traces matter more than weights for agent training at this point; without open trajectories the closed labs just keep extending their lead on agentic behavior even if every frontier model gets open-sourced tomorrow.

MIT researchers just replicated human muscles with AI-controlled fibers.
— Rowan Cheung (@rowancheung) 22 avril 2026
Inside each fiber is a sealed tube of electrically charged liquid and a tiny electric pump.
When the pump activates, one side contracts while the other relaxes, just as your biceps and triceps do when you… pic.twitter.com/3rFCXENoznMIT researchers just replicated human muscles with AI-controlled fibers.
