I think a lot of people don't really see past the wheelchair, I certainly didn't for a long time. Some people try as an educational experience to live for a day in a wheelchair, but that's easy, spending a whole day sitting down is something desk workers do anyway. It's a completely different thing if you don't get to use any core muscles. I wanted to try that, but couldn't go even ten seconds without cheating. Even with all kinds of assistive technology it's extremely hard. Also the lack of bowel control must be a total nightmare.
The whole "paraplegics can do anything, they're just like you and me" schtick that normal people are fed is a nice coping mechanism, but I think it may be holding back funding for research into real solutions.
