Fortran meets AI

Story time My father studied at Faculty of Electrical Engineering at SS Cyril and Methodius University in Skopje in the late 70s. I studied at the same faculty and university 30-something years later and got my Master's degree at Faculty of Computer Science and Engineering. While back, during my studies I found one textbook from the courses he took, Fortran IV. Here's the photo of it: Some of you reading this might know what Fortran is (programming language), but I presume almost none of you seen problems solved in the language or punch cards. Yes, punch cards. Back in the days, people used to code on punch cards and that was included in this course. Punch cards meant that every line of code in a program had to have its own card. So if your program had 1000 LOC, then you had 1000 cards. How that looked, more in this video: Most interesting thing: there was an exam inside it, his exam from almost 50 years ago! Here it is (fyi, the language is Macedonian): As you can see they weren't sol
