I'm cheering for SpaceX for doing more towards spacefaring, but I'm very skeptical and think this will, at least, end up being negative PR to them, and, at worst, a lot more.
That said, I suppose we need to apply Elon Time coefficient here, and the Moon mission will end up being in 2019 / 2020. Still, I'm very excited, because for the first time in my life, the possibility of humans going to the Moon again within my lifetime feels actually real.
The timescale is bullshit-- the past two failures have both pushed things back a ways, and at this point I'm not optimistic there won't be more failures soon (although I strongly believe they'll succeed completely in the long term regardless). Things would have to go perfectly for this timescale to actually happen.
But what really makes me nervous is the thought of it going wrong and people dying. That would be pretty terrible. I feel like they need to do a lot more testing before they can send anyone around the moon in a mere 18-20months. That's just too soon. F9 is still having confusing failures after years in service. Falcon Heavy hasn't even flown once yet, nor Dragon 2.
