That's how science has always worked. It's rare to go from research to consumer goods in less than 10 years. Often it takes more.

Lasers were invented in the early 1960's. And there was a bunch of hype for half a decade. Dozen years later people were referring to lasers as a 'failed' technology.

Transistors invented more or less in 1947. Twenty years later in 1967 my parents bought a BW TV, with tubes.

LED's. First invented in 1927, practical devices 40 years later in the mid 1960's. Widespread use in lighting, not until 40 years after that.

Well, you always have to wait for the patents to expire. Then development can flourish, for a time.
