...I think it's interesting to speculate on what technology will look like a hundred years from now. I really do believe that some kind of mind interface is the next big leap since it's already in it's infancy in the early 21st century.
I think it was an episode of Voyager that sparked this idea (and it wasn't until recently that I came back to it): it was the one where the Relativity was using 7 of 9 and Janeway to stop some time-traveling Una-bomber, or something (saw it a long time ago, can't you tell?

).
Anywho, there was a shot of someone sitting at a console of this 'timeship', inputting commands with their hands, and it got me thinking: will we even need our hands at that point?
There was something I recall several years back...I don't remember who said it (either Roddenberry, Berman, or someone else), but they were referring to the progression of modern-day technology and how it was getting increasingly difficult to keep Trek ahead of its time. Looking back on the new Trek movie, it's interesting to see how much was kept 'tactile'.
