The technology we have now is amazing.  I grew up with it, but I know enough people who lived without it to appreciate it far more than most my age.  I’ve also spent time on new colonies, where the use we made of holotech and gravtech back on Earth would be considered wasteful.  Still, we had when we needed it.  It is really hard for me to imagine having to use rockets to get into space.  Those are dirty, dirty launch systems compared to grav plating.
