After using mostly Apple and IBM computers and Unix I came to ESU which had adopted Windows PCs. There is so much software out there for Windows that I slowly adopted it too. Similarly, over the last few years, as I look at other people's AI work I have been forced to read more and more Python code. My AI code library previously consisted mostly of BASIC, PROLOG, C/C++, and LISP programs. To this I have now added 50 or 60 PYTHON programs.
