I would go even further and state that TIOBE is deprived of any meaningful value. It's basically a index that tracks web noise. I mean with TIOBE, C++'s ranking goes up if someone writes a blog post with a joke that goes "A C++ developer walks into a bar...".

I wouldn't be surprised if this post in HN is contributing to the bump.

TIOBE is what you get from garbage-in.

I would bet that C++20 led some bloggers to post random stuff with C++ in it.
