I agree that they took a while to commercialize, but they were new technologies. Smartphones, streaming, etc. are not new technologies. They are extensions of old ones, or in the case of smartphones, a systems integration problem.

I think we're talking past each other a bit. I think there are technological leaps and sociological leaps. Most new tech is a sociological leap: it changes society but it does not make use of anything radically new.

I think the only real technological leaps in the past twenty years have been maybe crypto, and some things happening in biology. Notably absent is renewable energy, which was largely developed many decades ago but is now being commercialized due to process improvements.
