The only fly in the ointment is that we were born too soon. Most of interesting things will happen when we're past caring.
I think this is what everyone, from Cro-Magnon Man onwards, must be feeling when they (ha, gender-unspecific pronoun which the purists will carp at) contemplate the future! I also hereby propound Deepa's Theory of the Ascent of Humankind (which, of course, must have been thunk and expressed much better by someone much earlier) that the future, even in our own lifetimes, will consist of inventions and discoveries that we cannot or do not envisage now, or which we believe at present to be impossible.
