Roleplaying may slow down. It'll dip and surge, come and go. There are lots of factors involved like the time of year or world events (like the pandemic). But it'll never actually die because it's always changing - evolving. Silly as it may sound, it's a very fluid art form practiced on a wide variety of platforms. While it may seem to some to be slowing down, in other areas to other people it may be growing in popularity.
