Carmack shut down Armadillo Aerospace before it got to that point. I don't recall where he spoke about it, but he has talked about this in the past.
Good for him then, but AFAIK he is still very much into space and I hope he'll have another chance even if it's gonna be funded by money Facebook gave him.
PS: Might be something changed by now, but I hope not. I really need to check latest podcasts / interviews with him.
Also I guess he run out of money when Armadillo Aerospace has failed and at least before he talked like he want to make second attempt in space industry and this will require a lot of money.
