Assuming that we mean just that the monetization of it didn't develop beyond like early youtube stage, I don't think it'd be that different from back then. Without the economic push, the developments would probably be much, much slower, especially on the frontend part. I think it'd still be useful enough to not just be treated as a fad and lose popularity completely, but it wouldn't be as dominant.
