Language bits and pieces that I have learned:

I have to agree with just about everyone here. Everyone is saying the same thing, it's just that some aren't thinking ahead.

First generation interface: realistic, easy to navigate for a beginner, and only changes your thought processes by a little (still 'human-thinking' as some would say), probably depending on what actions you take in this virtual world.

Second generation interface: I'll be damned if I'm willing to put up with reality everywhere I go. As R-Type said, 'it's just a place to get things done, now'. I expect that people who grow up with the neural jacks will get extremely used to a new and very complex interface which would throw newbies into convulsions.

Any language evolves. This is more, even, than a language: it's a whole protocol. What you feel is controlled by it. Anything you do is input to it. it will evolve at a tremendous rate, because you don't want to be stuck in a really simplistic world when you're capable of so much more.

In time, people will think in 'in-human' ways, if you judge humans by the same standards that (er, shoot, closed that window) guy who says people will think inhumanly does. Personally, I think it's not inhuman, it's just social evolution (by that, of course, I mean the evolution of society, not the biological evolution of man-creatures).
