This sounds good, for now. With time it will fade out of sight and of our memories just like digital eye enhancement (Unlike corrective laser surgery, with it you can see MILES down the road to read the STOP sign).

I am sure that some bureaucrat somewhere will delay it long enough till a lot of people can profit from it, and the general public will not be able to afford it.

But I am glad to read about such advances in R&D.
