I've been keeping tabs on this company for a couple years now. What they are doing is amazing.
They say they will have a product on the market in about 4 years. I've already got savings set aside specifically for investing into this, but I'm waiting to see if there will be any more breakthroughs with the non-invasive approach, and if those breakthroughs will be made by competition. I know Japan has something similar that is entirely non-invasive; however, it has a 7 second delay in response.
How does everyone here feel about cybertechnology?
