I think my point was that if everyone does the "not getting it until there is sufficient content" bit, there is unlikely to be a large uptake of the technology to capture, process and especially broadcast the medium.
I personally have no intention of being an early adopter, possibly not even on the crest of the wave adopter.
Not sure my eyes are HD compatible even with glasses on, let alone 4k!
There's a good concept called hype cycle having been created by a company named Gartner. It basically assumes that early adopters of new technology are most likely to waste their money, serving only to provide others with profits. From the buyers' perspective that is no good.
On the other hand technical progress will continue with or without our approval, so purchasing early on to enable new technology to become profitable is not really necessary. Early adoption may even turn out to be harmful as it might slow down mature product selection, which serves consumers better in the end.
If new technology is any good, it will sell. If it is in a status of not being really mature enough to be good, it is better to leave such things alone to allow market forces to clean up.
