Such an honor to be judging the @hackwithtrees hackathon at Stanford University this morning. Starting in the NVIDIA auditorium, of course.
Everyone is so young and smart. Something like 350 teams. Thousands of developers.
Largely seen as the best hackathon in the world.

This weekend I'll be at Stanford's @hackwithtrees hackathon.
I'm filming a documentary about it and interviewing tons of devs about the projects they're building.
If you're there and you see me come give me a high five. 🏕️
