UTF-8 can represent up to 1,114,112 characters in Unicode. And in Unicode 15.1 (2023, https://www.unicode.org/versions/Unicode15.1.0/) a total of 149,813 characters are included, which covers most of the world's languages, scripts, and emojis. That leaves a 960K space for future expansion.
So, it won't fill up during our lifetime I guess.
I wouldn't be too quick to jump to that conclusion, we could easily shove another 960k emojis into the spec!
