I think there is an element of it producing reasonable results because it is trained on largely seeing canned example output. In tutorials, the command that includes ‘hello world’ always outputs ‘hello world’, right? So it doesn’t take a genius to guess that <long blob of golfed code that includes the string ‘hello world’> should produce some output that includes ‘hello world’

Similarly in my explorations of this ‘pretend Linux’, it often produces whatever would be the most helpful output, rather than the correct output.
