New technologies in 2050

From what we can see today, it is possible to imagine what will be the new technologies in 2050.

One of the most progressiv fields should be medicine.  The longevity of human kind should increase enormously. We can also expect that it will be only the richs who could benefit from those progress.

The computers will surely be more and more like shelf, and become more and more thin and may be flexible like paper.

We can imagine the new computers more like newpapers that will change of content.
May be smartphone will be directly grafted on our body.
