The space ship is already being developed for the Commercial Crew program. The rocket is a new rocket but with the same engines and the same upper stage.

This does not seem so impossible. A couple of delays will happen, but all in all, there is no fundamental problem.

I agree, there is no fundamental problem. But that couple of delays will bring the actual date much further away than "late next year". I'm sure Elon Musk is capable of great things, it's just that he's very obviously squeezing the people in his companies to the limits and beyond, by publicly announcing objectives that are just about possible, provided that his employees will work day and night for entire years.

I simply don't understand why people are always up in arms about his companies being so bad with their employees. Lots of companies push people to do more ours. God knows, I have worked insane hours for far worse reasons.

Plus the actual evidence for Elons companies being far worse then anybody else is not really there.

Plus, its not like all those educated people that work at SpaceX would live in the gutter if they can't do the job.

That's a completely different matter, I just meant to say that Elon Musk's estimates are often extremely optimistic.

You know (if you're a developer) when you're working on a very exciting piece of code that will do wonderful stuff, and you have clear in your head what you're doing and how to do it, and think "it'll take me an hour, can't wait to see it working" and then at 4 AM you're still there, always in the same state of mind, with half of your brain asleep and the other half still perfectly focused on the result? Yep, I think that's Elon Musk. Still in the splendour of his early twenties :)
