I don't disagree with your general point, but the truth is, there are a lot of adaptations and assistive input devices people use for computer input all the time. There are lots of ways a techie with a functional brain can continue to work even after quite severe injuries.
Which, you know, is no problem at all if you're actually so injured you can't work.
I wanted to be truthful and didn't know off the top of my head what, say, the median time for a claim to be accepted was.
I remember it being something like 2-5 months to get a response, so multiply that by the number of appeals (up to 4, I think) and my ballpark estimate is that the median time-to-acceptance for all eventually-accepted claims is around 6-18 months.
So, I figured saying "could take months" was a more honest thing than saying "could take years." If the median time were greater than a year, after all, "it could take months" is still true, but the converse isn't true! If I had said "years" instead of "months" and was wrong, someone could easily have replied, saying, "You're exaggerating. The median time to acceptance is 9 months, not years. The claims that take years are exceptional cases."
In any case, I didn't know, so I wanted to err on the side of intellectual honesty. That'll teach me. :P
Also, I don't know if you (and the other person who replied with the same comment) have ever heard of Wiio's Laws: http://www.cs.tut.fi/~jkorpela/wiio.html
One corollary of those laws is this: "If nobody barks at you, your message did not get through." :)
I don't even disagree with you, but have a tangent to share:
Have you seen modern robotic prosthetics? I don't want to make light of anyone's situation, but I honestly think we are mere decades away from replacements that are better.
