We’ll need to work on power. Unlike process speeds we’re not seeing huge increases in battery technology, we’re not really rapidly adopting alternative forms of power. In the next 100 years we’ll need to figure out better and more efficient ways to power the planet. Solar will be extremely important of course. In the next 10 years the “internet of things” is what I think will be a big leap for technology. Any object will have sensors, storage and a net connection in some way. With everything “talking” we’ll have smarter everything and huge databases of sensor information to make better decisions about everything.
