Elon danced at the Chinese Gigafactory. They've become productive in record time.
But his reason for dancing most recently is the fourth-quarter sales results for Tesla. They've done well.
Likely the reason for dancing next year will be similar results, and a successful inauguration of communications on Starlink, and a successful re-entry test for Starship.
Elon Musk is being Tony Stark. It's good to be Tony Stark.
If a few of my sons go to Mars, Earth will be safer, until they develop the mass drivers.
