That will get worse yet most likely. Younger people no longer produce public text to the extent they did prior to the the smartphone heavy era. Supply of that blog style content will continue to dwindle as the producers age out. I'm sure there's a stability point it may reach, of course, because some tiny percentage of people will always want to write long-form.
Younger people TikTok, they Instagram, they chat in private conversations with eachother, they occasionally post short messages in walled gardens like Facebook, they YouTube, they listen to music, they watch Netflix & Co. That's what they do. They do not persistently write LiveJournals, Tumblrs, blogs. That pre video/audio-focused era is over and it's not coming back (even if there's occasionally a bubbling up of hipster fakery centered around how cool it is to write text).
