Just recently, I thought a lot about what we will be using in a decade, what our lifes will be lead by and what technology will most likely develop into. I wrote a Hub about the Internet of Things, one development that will, in my opinion, be the biggest change in the near future.
The IoT is a scenario in which all the things surrounding us are connected (the reason for this being so likely to come is, that the technology is already being developed). They are able to communicate with each other and act based on the amount of information they are able to store.
An example would be the following: you go to sleep but you don't have to set the alarm because your smartphone already knows when you'll have to be at work the next day. So it calculates the average time you need for breakfast, to drive to work and to get ready, takes into account all possible and real delays and sets your alarm based on this information. I could go on, but this explains it pretty well.
The interfaces will change too, of course. Maybe we won't have smartphones anymore but wristbands or tiny screenless buttons, who knows?
But one thing is for sure: the world won't be looking much different than it is today, because we still have chairs, right? And they have been invented a long time ago.
