Quoting James Burke:

"At no time, did an invention come out of thin air....
You just had to put a number of bits and pieces
that were already there, together in the right way."

Therefore we can advance using our present technology 
and evolve for many years,
without changing our present resources.
It might not take a new discovery to make
our technological dream come true.
Our dream may lie simply in understanding,
and utilizing what we already have.
