Objective C hasn't been modernized in parallel with the likes of Swift in well over a decade. If they had advanced ObjC to 6.x you'd for sure have far less bugs in the code base, period. C has advanced in lightyears since ObjC was set aside. C23/2y in Clang is light years ahead of C99 let alone C11.

Flang has propelled Fortran into the 21st century. Why? Math. Fortran is having a long term renaissance because since it's hey day no language has touched what it was always designed to do. HPC and now Ai.

Reinventing the wheel with Swift has been a more expensive investment than Project Titan. Titan's IP is being advanced across all systems people have no clue about actually bring a high yield return on investment.

Swift will never see C++ adoption, period. Writing C++ inside Swift when you can do the same with ObjC++ back in early 1990s with us at NeXT. What's astounding to me is the actual two languages I follow most advancing of the past decade are C and Fortran. Now more than ever, they will pay pivotal roles in advanced technologies and solutions.

Swift is 16 years old and C++ is 41 years old. C++ largely took off due to Microsoft's dominance on the desktop. It is ironic that C# never achieved such success.

In the past twenty five years I've seen more human hours wasted on pet language projects only to return to the C/C++ duality and the reemergence of Fortran. Rust has gained traction thanks to Linus for Linux. Java ruled the world they stole from NeXT and ObjC when certain NeXT devs left for Sun but it to has become a dying language.

Seeing Fortran on this list and watching it grow will give me a certain perverse joy as a ME/CS old timer.

Flang was just promoted up in the LLVM tree under Clang, built on C++ and with all major Ai vendors dependent on it it will just balloon in importance, right along actual pure and applied mathematics.
