I am really troubled by the way traditional companies exploit workers, and see that as a major problem of our age. If you could show the world that a worker coop could succeed doing something highly technical like robotics, it would serve as proof that the cooperative model can work for more than just chicken farms. I'd be focused on growth like a silicon valley startup to some extent, but quality of life for everyone in the organization would be a big deal.
I'm also kind of curious about B-corporations, which allow a specific public benefit to share standing with profit as a legal goal. This would be more silicon-valley friendly as far as funding, since worker coops don't have the same revenue generating opportunities for investors. Though the coop could agree to some kind of internal "revenue tax" to pay back investors or save money.
I'd love to see some wealthy people just give their money away to talented organizations that want to spread public good. What I'd love most would be to just work on open source robotics that help the world. I've been developing a system for 3D printed robotics that use as few non-printed parts as possible, making it easier to collaborate online with hardware designs. I don't typically even use screws, since sourcing them can be expensive and slow - most parts just snap together or interlock.
An alternative plan though is for me to get rich the traditional way and then use my own money for good, so I am going to be checking out the new YC RFS for hardware whenever that comes out. I have some good ideas about improving life in the kitchen that might be workable. :)
