This might be a stupid question, but how is this different from cross compilers? Is it more natural and readable?
"Cross compiler" usually means a compiler that generates machine code for a machine other than what it runs on. For example, a compiler that runs on X86_64 but creates binaries for Atmel microcontrollers.
You might be thinking of transpilers, which produce source code in a different language. The f2c Fortran-to-C compiler is an example of that.
In my experience, transpiler output is practically unusable to a human reader. I'm guessing (I haven't read the article) that IBM is using AI to convert COBOL to readable, maintainable Java. If it can do so without errors, that's a big deal for mainframe users.
Transpiler, that's it. And thanks for your answer.
