One gripe i have with the existing set of hackathon style / builder grant programd is that it encourages smaller projects

I wish we had better incentives to build things that are durable

Stuff like Enso, Ink and Switch, Bret Victor, etc

Multi-month hackathon with checkpoint prizes could be interesting
