I read an article about a company that makes glasses that allow color blind people to see colors. I contacted the company telling them that I used to have a pair of contact lenses that cured extreme deutan condition (extreme red-green color blindness) and wondered if they had any products that would cure this condition for me.
Their response was “No we have nothing like that. Our technology is much more advanced than the red lens technique.”
I thought to myself “if the technology existed in the 70’s and does not now, how can the technology be more advanced now?”
It seems to me that technology has digressed, not advanced if something that used to exist no longer exists and a void is created.
