If I go on itch.io right now and pick something at random, the likelihood of it being both made by a teenager and involving written storytelling is quite high. Likewise a huge hit of the last decade was Undertale and it had the kind of success where I recall seeing kids draw the characters in chalk on the sidewalk. The evidence indicates that writing never went away, it's just not upheld by large productions(and even then, Nintendo regularly eschews voice acting).

To me, there's nothing sacred about text, it's just a medium.
