Technologi is stuck now. All companies do is upgrading existing techs. Just look smartphones: IPhone 1-4 had many differences, each were unique, and iPhones 6-X are almost the same, with small addtions.
Reminds me of this brilliant fellow: Charles H. Duell was the Commissioner of US patent office in 1899
Most famous utterance: "everything that can be invented has been invented."
