That is placing too much emphasis on a single individual. If Besner hadn't been born, someone else would have observed that running compressed oxygen through iron helps control the carbon content of steel. If Ford hadn't been born, someone other rich bastard would have observed that he can use an assembly line to usher in the era of consumerism. I still hold that if it is out there to be discovered it will be discovered, and it doesn't matter who discovers it. This sign is implying that the people being born are idiots. I find that insulting.
