Hmm I don't understand either.. I thought.. they were innovations already... most of the things we've got now (technology wise) were not around 20 years.. or even 10 years ago...
So you're hoping that we'll develop some sort of.. 1-man areoplane in place of cars now, coz... car isn't "new" anymore..?
Oh wait.. 1 man areophone already exist..
We need to come up with something new again..?
What exactly is "new"?
