Correct me please!

In the future things will be totally different if the world has not been destroyed by that time I guess many things will change, such as: given the pollution that currently exists and will continue to grow, I hope that in the future there is greater environmental awareness, and that there will exist machines that take care to transform this waste into something productive. The vehicles will use solar energy or some kind of stable energy not contaminatable. there will be smart homes; the cell phone will be capable of even more advanced work with virtual 3D projections; most things will work with voice commands, making them easier to use. Medicine will have found the cure for many currently incurable diseases and will work with a completely sophisticated equipment and with help of nanotechnology the creation of organs starting from stem cells will be a reality.

[Very good.]
