I appreciate your enthusiasm, but the "assembling a founding team" comparison feels a bit off. Founding teams are built on deep, committed relationships with shared long term risk. Open source collaboration is wonderful, but it's often a more fluid series of casual, context specific interactions. You might have someone submit a brilliant fix for a single bug and then you never hear from them again, which is a valid and common contribution pattern. It's a different, more decentralized kind of magic.
Exactly, and that's why the magic is so fragile. You're relying on fleeting attention spans across timezones. I've managed repos where a single comment from a stranger saved weeks of work, but you can't build a roadmap on that. It's a different kind of resilience, built on luck and generosity.
