Sure if we could do it now with a room sized device, then its just a matter of scale. 10 years is reasonable if that was the case....
BUT, we aren't even close to this level of technology yet. Sure there have been lab expierements with a alphabet on screen where people look at the letters to type a word. But it takes forever. We have a LONG way to go before thinking about brain implants to control devices.
If you can't say anything nice, don't say anything at all. That's all I'll say here. Put it this way though, it'd be nice if there were an easy way to make the rest of the world smarter and change most people's way of thinking, at least where I live.
One of the many regions of ideas that should be for once left to the imagination. We have not really started on the road of using our minds and for the lack of want and teachers the best we can come up with is using tech to "enhance" how we interact with our physical domain by putting physical things inside our body. Its a step back but just maybe most have to fall before they can move forward. Necessary evil?
i think the biggest problem is heat dissapation. i mean, your brain dies at 108 degrees F (42 C), so those processors are going to have to be LOW power or external (outside the brain). could you imagine getting brain damage on the tissue around your implants from the heat. anyway, it seems like a viable concept since they have been implanting chips on people's brains for years in medical applications.
I am very excited about this type of technology because I have bad wrists from typing, lifting wieghts, and a motorcycle wreck so i would be first in line for this type of implant that would let me use computers without having to use my hands.
