Did Musk created his rocket all by himself? Or did he merely overseen the development?

Also, Jobs did far more than iPod/iPhone. Both in Apple and in his other companies.

Everything we have heard on the subject suggests he has done meaningful engineering work on the rocket. This fact should not at all minimize the contributions of others, which are also very substantial. Nor should it take away from the accomplishments of Steve Jobs.
