Mojo is a new programming language meant to eventually be a superset of Python (ie all Python code is also valid Mojo code) but with features allowing it to be much faster. It's being created by Chris Lattner, who previously created LLVM, Clang, and the Swift programming language, among other things.
The TIOBE index is an index I found that is supposed to track programming language popularity. I don't know a whole lot more about how they decide, but eyeballing it, it seems basically reasonable.

The question is whether Mojo will make it onto the top 10 list by the end of 2026. That would put it around the present popularity of Go, PHP, and SQL.
To qualify it should appear to be basically stable in remaining within the Top 10. I will err on the side of assuming that if it has been on the list then this should resolve YES, unless it was clearly a flash in the pan that was on only briefly and then sank fast.
