Frankly, is one of the best things the internet and what computers have brought about. A person physically can not run out of interesting things to peruse. That's pretty great, t'me.
I'd argue that just because the total amount of
media is increasing faster than one person can consume does not necessarily mean that the total amount of
interesting media is, because what a person considers to be "interesting" can be arbitrarily limited.
For example if I was only interested in sensationalist white-focused speeches by KKK members who were formerly WWII Nazi members, I could probably consume media at a much faster rate than what is being produced, and would eventually run out of new media to peruse. Or I might be interested in, specifically, "shonen anime with fairly complex characters and plot, with a strictly defined power ruleset, that is expected to last longer than 8 episodes but is currently shorter than 200 episodes". In such a case I might find it very possible that I am indeed consuming media much faster than it is being created, making "running out" a totally viable concern.
Estimation gets even more complicated when we consider that the average person is not always "in the mood" for any particular piece of media; I might enjoy reading about new developments of space travel, but that doesn't mean I'd consider them interesting when I'm really in the mood for an anime. And then is even further complicated by the fact that many forms of media require some cost to access, be that in time or money, meaning you don't necessarily have access to everything.
Just because seven billion people can create more total content than I can physically consume, does
not imply that they can create more content that I both
want to consume and have access to at a cost low enough to make its consumption worthwhile.
