Point to nearly anything that has dramatically changed modern life and you will see the arm of the state involved: GPS, internet, the airplane, etc. The best argument I'm aware of for private enterprise producing really novel products is Bell Research, however they were a regulated monopoly, not a competitive industry and the state authorized 10% additional charges for investment.
You can make some arguments about things like iPhones but that device depended on a huge state funded or regulated infrastructure to be useful (e.g. cell towers, internet), and it was essentially a very polished cobbling together of different components (microchips, batteries) that were developed from many decades of state supported / regulated monopoly research.
Business is very good at taking something off the shelf and making money with it. It's very bad at sustained investment that might not be profitable more than a few years away.
