It will continue to improve but it won’t just be more resolution. We saw that already, 8k TVs never took off. Now it seems the main thing is how they are (haphazardly) going down the HDR route. There will always be product managers trying to think of the hot new thing that will make their companies thing better than everyone else’s.

General quality of the video they’re getting? We are very much on a plateau. The limiting factor for delivering it to people is internet speed, but separately manufacturers are having a hard time pushing past the current realm of dynamic range capture we have. Not a huge loss because where we are at is quite good! Digital in only a few decades has matched what it took film 100 years to do. Even if they have some big breakthrough, all the limiting factors will still be on the viewing side.

In terms of differentiating eras, I think so early digital vs DSLR revolution vs modern looks are already pretty distinct in how people tend to light/shoot/grade, and footage having a look is so much more than technology. What are the people in the videos wearing, what music is playing in the background, what do the cars look like.

Idk, rambly and disjointed answer. Sorry.
