01 Physical AI
“The forearm and hand are more difficult than the entire rest of the robot.”
Elon Musk, Tesla CEO, Q3 2025 earnings call, 22 October 2025.
“…the muscles that control your hand are actually primarily in your forearm.”
Elon Musk, same call.
02 Every hand teaches
A recovering hand relearns, rep by rep.
An everyday hand uses chopsticks without a thought.
An expert hand shapes clay by feel.
The internet learned how we write. The next AI learns how we move.
03 The data robots lack
Hands are the data robots lack.
Every consented rep pairs motion and muscle. Other apps record what a hand did. SOMA also records the forearm muscles behind it.
“…we can make a gigantic progress whenever we have access to data.”
Wojciech Zaremba, OpenAI co-founder, on why robotics stalled. Gradient Dissent podcast, 2021.
“…looking at pictures of humans doing things doesn't tell you the actual detailed motions that the humans are performing.”
Ken Goldberg, UC Berkeley, 2025.
04 One band. Every hand, anywhere.
- rehab
- mentoring
- operation
05 Consent first
Recovery comes first. Data is shared only with consent.
Patients use SOMA to get their hand back. If they agree, each rep pairs motion and muscle and helps build a model of the human hand, which robot makers license later. Patients choose, and can say no.
