You give humans so little credit and are so ready to dump on the manned program. Good thing you won't be going.
The manned program exist for the men, and the vicarious aviators. It is wasteful. Given the advances in robotics just in the last ten years, if all focus was turned to taking advantage of those advances--what we could find out, where we all could go, electronically.
Instead, resources will go to trying to maintain that lucky celebrity who gets to ride.
All evidence points to the inability of humans to live long-term in space, anyway, no matter how many zillions we spend to manage that fact.
