|
| This is quite literally what the Marvel / Star wars mass
| media slop is, a sort of syncretistic version of every pop

|
| It's a sort of media masturbation, hooking your brain up to
| itself and feeding it its own output, what the large studios
| are already doing with their franchises, just on an
| individual level. You'll basically sit in your own never-

|
| This isn't inherently a bad thing but I don't believe it's
| without its costs, one of which being that with everyone
| watching (potentially) completely unique media there'll be no
| shared cultural artifacts to communicate with others about.
|
| VivziePop may have started as a small creator but the recent
| creations such as Hazbin Hotel have now become things where
| the enjoyment can be shared with other fans, which in some
| ways is the secondary purpose of all media. Media enjoyed
| alone can still be rewarding, media enjoyed with others can
| be much more than that (except for going to the cinema with
| strangers, that can disappear immediately).
|
| It seems like a common idea that if we can just generate a
| practically-infinite stream of media then we've solved some
| kind of problem with there just not being enough "content" (I
| hate using the term in this way but it's concise), and while
| I do sympathise with the points of view from people that
| can't find things they like, I also don't really believe that
| "Content is a problem".
|
| More variety itself isn't a problem, but I'm not convinced
| that in general there's a _lack_ of content. Humans have
| already reached peak saturation in terms of the sheer amount
| of text, audio and video that's created every day. No single
| item of media is itself a problem, but perhaps the total
| aggregate of everything isn't helpful.
