I was recently accused on another blog of repeating a defeatist mantra.
My “mantra” has always been WE CAN GO NOW. The solutions are crystal clear to anyone who takes a survey of the available technology. What blinds people is their unwillingness to accept the cost of making it happen.
There is no cheap.
