Thoughts to ponder...
Hmmm, let's see.
Here is one that has been in my head a lot lately:
Nanotechnology, specifically graphene.
From Wiki
Graphene
(/ˈɡræf.iːn/)[1] is pure carbon in the form of a very thin, nearly transparent sheet, one atom thick.
Graphene is remarkably strong for its very low weight (about 100 times stronger than steel[2]) and it conducts heat and electricity with great efficiency.[3] While scientists had theorized about graphene for decades, it was first produced in the lab in 2003.[4] Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the bipolar transistor effect, ballistic transport of charges and large quantum oscillations.
So, it is strong, it's the most impervious material known (even hydrogen cannot pas through it), it is very light, it has semi-conductor properties, it conducts heat and electricity far better than gold. It can be made to form electronic circuitry far smaller than anything that has ever been done on silicon. It can 'self arrange' circuits. AND it can be
photovoltaic (can convert light into electrical current) or
thermovoltaic (produce electric current from heat diferentials between two surfaces)
So among other applications it can be used to create self-powered microscopic programmable devices.
It was only discoverd in 2003 but it has been the subject of fantastic discoveries and will change our world in ways that have only been previously imagined. I could go on and on but lots of better minds than mine are already on it.

One atom thick?!!!
