No, Akalabeth is right. SC was and will likely be the largest crowd funded game for the foreseeable future, but at this point, its failure will not be seen as an indictment of crowdfunding as a concept.
If anything, SC has already had all the impact on the crowdfunding scene it was going to have; I think campaigns these days are very careful to stay in scope or to have developers with proven track records on board.
Like, while I wouldn't give Chris Roberts any more money, I will definitely consider backing whatever Harebrained Schemes are doing next; similarly, I've backed Project Wingman purely on the strength of their existing demos and their commitment to not expanding the scope of their project despite taking in a lot more money than what they were asking for.
