Do you doubt it was developed in 1996? Do you have evidence that the cost of production has significantly risen?
Otherwise, you seem to be repeating the old economics joke:
"The young economist looks down and sees a $20 bill on the street and says, “Hey, look a twenty-dollar bill!”
Without even looking, his older and wiser colleague replies, “Nonsense. If there had been a twenty-dollar lying on the street, someone would have already picked it up by now.”"
