As an 80's baby, the greatest technological marvel I can remember is the advancement of the internet. The article listed here yesterday made me wonder -- What are your predictions for 2020? Here's mine:

1. artificial limbs controlled with the mind. There are already advancements in this area, and I am interested where it'd go in 10 years.

2. solid state fuel cells are the main power source for vehicles.

3. 1 Terabyte thumb drives are old news. They are commonplace.
