Only 100 years?
Let's see, clothes would be like the 1960's again, either that or Members Only jackets would be vouge, and the 80's hair rules again. (Mullets galore.)
PC's would be museum pieces. I think devices like cell phones will take over that role as new GUI's are developed that allow for speach based use, and the need for a qwerty is eliminated. Perhaps something that tracks your eyes on the screen and allows you to navigate the system that way.
Hopefully the environmentalist/global warming caste will have gone the way of the dodo bird, but I'm sure some new "fear" will have come along to pre-occupy our minds when we are not using them for work or play.
I think I would look into a quick report of history, and then get on the lecture circut and start making money talking about sleeping for 100 years, and write some books. (Well, whatever they are going to call written material 100 years from now.)
Will we even have written material like we do today? Why not speach capable mini computers that are everything in one small package. It can connect you to the world, all you need to do is say "do it."
I'm assuming FTL includes space travel, so I'd go there. Always wanted to see the stars and other places off world... LOL
