Often media forms make sense in their original context and make less sense the more the current context differs. In classical music orchestras, for example, many identical instruments play simultaneously, unlike in jazz or blues/folk/rock/pop. IMHO that makes more sense in a context without amplification, without few sounds are that loud (making it more special and dramatic), and in an industrial society where the common solution is lots of workers performing identical tasks. We can also think of media forms as technologies and see them similarly.

For video the context is shifting: As an hypothesis, the length of the media could be viewed as ROI for the required commitment. In the context where watching a film required going to a theater, 30 seconds or 30 minutes would be poor ROI - you plan, travel, give up everything else you're doing, pay ... you'd be unhappy if it was over in 30 minutes. In a context where the commitment is pulling your phone from your pocket and tapping it a few times, 30 seconds can be fine and you usually wouldn't want stand there for 2 hours.

Each form has advantages and disadvantages; I think it's a normal but clear error to say what came first, what we're more familiar with, is better. We do and will lose things with change, but we'll gain others. We don't lose them completely - there are still classical orchestras though no more riots over a premiere. But the energy of innovation is not in classical music, jazz or rock - people listen to the old stuff mostly - and maybe less in film. I expect that many of the young, innovative geniuses who in the past would have made classical music or jazz or rock, or written novels, are now making computer games - they are embracing the newish frontier, and the exciting thing of their youth.

So far, film seems to coexist pretty well; there seems to be plenty of creative energy on the high end, but we'll see. What about small independent films? What about film schools?
