What is the greatest invention of the 21st century so far?

Answer 1

Genetic decoding and engineering
"So far"...It's only just begun to change our lives.

Answer 2

LOL. The 21st century is only 7 years old! Anything invented now would take a long while for it to become mainstream let alone give us adequate knowledge to rate it! Take HDTV that was done in the 1990s but it takes awhile to perfect it....

But looking ahead 50 years, I think that the greatest invention or find would be that stem cells have the ability to reverse some of the worlds worse diseases and disorders. And in the future it will become common medical practice.
