The Udemy Lazarus instructor IS getting annoyed with me

After laying out my case. His response was “You have to remember that since I’ve been programming Pascal since the mid-80s and Delphi since its launch in 94, I have accumulated huge libraries of code, so I am not at all keen on breaking backward compatibility for the sake of incorporating new syntax“. Except it’s not new syntax the page I pointed him to was written in in 2013… 11 years ago. Also the course shouldn’t be about his code. It should be about teaching relatively current developments… IMHO. He could have responded “I wasn’t aware of that. Thanks for updating me”. But unfortunately some people just assume is someone takes a course they must be new to it.
