How is it a trap if languages are able to move away?

  Not all do, some stick with their decision to live with LLVM, e.g. Swift, Julia, Mojo,...

    But isn't there a reason why so many start with LLVM ? It's highly optimised. I think mojo is not LLVM but mlir

      It is the modern version of a compiler construction toolkit, which by the way isn't a new idea, even though so many think LLVM was the first one, One example from 1980s, there are others to pick from as example, https://en.wikipedia.org/wiki/Amsterdam_Compiler_Kit https://en.wikipedia.org/wiki/Amsterdam_Compiler_Kit So naturally a way to quickly reach the stage where a compiler is avaible for a brand new language, without having to write all compiler stages by hand. A kind of middleware for writing compilers, if you wish. MLIR is part of LLVM tooling, is the evolution of LLVM IR.

      Mojo uses mlir for high-level ir and most optimizations but codegen is still done with llvm, albeit in unconventional manner.
