5 years? That's not too far into the future, but lets see..

The electricity grid will be "smarter". Hourly market allows near real time monitoring of consumption and prices, and electricity could be bought by consumers on the cheapest hours automatically. We are entering a phase where services are being invented to make use of hourly metering. This should be an interesting 5-year period.

Medicine will see advances for sure, but it'll also see challenges in all these swine/bird/whatever flus that keep surfacing. A cure for cancer in humans would be remarkable.

I'm also hoping to see them start building a manned lunar outpost by then.
