that's very hard to predict...but my guesses are:
1. We will have PCs having computing speed equalling Super Computers of today's world. Moreover, portable computing devices (which are called laptops/notebooks now) will be wafer thin and foldable.
2. Flying cars will certainly be a reality.
3. Space travel will be a lot cheaper and many people will be able to afford it (as against nowadays when only Multi-Millionaires can think about it)
Just wild guesses:
Sugar will be somewhere Rs. 500-600 per kg.
Rahul Gandhi will be the PM of India
