If we only knew for sure what the people of 2050 would desire, how rich we could become! I believe computers and hand-held devices of today will become even more important to mankind. They will become smaller and more compact with even more uses than one can imagine today. Hopefully, gasoline automobiles will have become practically extinct, helping to save natural resources and providing us with even more reliable and economical transportation.
Of course, we cannot know this for sure. However, here are some things that I would guess we will develop in the next few decades.
First, I think that there will be more computers doing more things for us. I think that we will have things like computers that can act on voice commands very reliably. We might even have computers that can drive cars for us so we do not have to drive them ourselves.
Second, I would imagine that we will have cleaner forms of energy production. I think that, by then, we will have developed ways to make fuels by having algae metabolize them. I think that we will have ways to tap the power of tides and waves. These things will hopefully allow the world's population to keep growing without so much impact on the enviroment.
