Assuming I don't get to retire until I'm 67, I have 34 years of work left to do.

Thirty four years in this industry, at this time in history, is centuries in normal human time. 2042 will probably be more different from 2008 than 2008 is from 1974. Which is in turn more different than 1974 was from 1940.

In 2042, will we have computers? Will we be computers?

I doubt I'll have the luxury of working the same job, same company until 2042, even if I wanted to do such a thing.
