Just like the luxury watches market ceased to exist when you could buy quartz watches for 10 bucks.
Except in this case, the quartz watches would be better quality than the luxury watches
I'm not sure your analogy has teeth.
Well the privet to luxury was due to quartz watches taking their core business, and now Chinese superclones are in the early days of threatening their luxury business. At a certain point it’s hard to care about the residual difference.
