First you complain about people not understanding how machines actually work, then you make it perfectly clear you've no idea how object oriented languages are implemented. In C++, code still goes in .text sections, and data is still on the heap (or possibly .data or .rodata), so the mixing of code and data is an abstraction.

"Object orientation mixes them up and probably does more to lead to exploitable code than anything else."
Wow, what BS.

BTW, I also grew up in the 80's on microcomputer ROM BASICs, and while I had unlearn bad habits when I went to real languages, I did learn a lot about how to solve problems.
