A VC invests large amounts of money (which isn't their own) for financial gain. That's very different to chipping in $10 of your own money for something you want to see built that probably won't be built otherwise.
I disagree. VC's put money in enterprises to get more money out. But their transaction is just money -> time -> more money. Kickstarter isn't the solution (there needs to be a platform that has legally binding contracts that the funded party deliver within some time frame or face fines / reimbursement of funds for fraudulence or negligence, the same way some investors can go after their interests if they abuse the money) but what people want is money -> time -> thing they want.
And I think it is the only way to produce information anyway, so refining the technique and recognizing its value is economics is huge.
