hmm.. i dont think theyll just die. theyre so young, and lived long enough to be more than a novelty.
speaking of novelties, i think thats what a lot of interactive comics are. not gif comics - they have a place inbetween webcomics and visual novels - but like, game-type comics. i dont see the fundamental medium of comics changing like that, when movies and video games and visual novels already exist and they arent comics
superhero comics might die out. or become significantly less dominant. marvel and dc will either die or change their game significantly. (also, i dream beyond dreaming that BL will die out but ik it wont bc straight women are awful)
i think comics will become a lot easier to publish independently, therell be more comic publishers on a range of sizes and specialties. theyll be taken more seriously, but still capable of being fun. obviously, print comics will die. almost entirely. that could make it harder to make money on comics, or easier - maybe being paid to publish online, by fans or publishers, will be the new normal, or everyonell be scraping by, because marvels no longer forking out for their select few, shite artists (and two or three blessed talented ones).
i think more people in the mainstream comic industry will do it all themselves. thats what you see, when someones moves from webcomics into big-leagues - they still write, then draw, then colour. maybe thatll make comics a harder job, but better paid. itll also increase quality, i think. unless an artist and writer work really well together (like mckelvie and gillen) it damages the comics quality, because theyre missing that communication.
or maybe we'll all be dead.
