I started my career programming in Vim on VT100 terminals (https://en.wikipedia.org/wiki/VT100 https://en.wikipedia.org/wiki/VT100) - yes, I am old. There was no IDE, auto-complete, visual debugger etc. You really had to think before you typed any code. Even fixing compilation error was a pain - you had to note down the line number and the error, go back and open vim, fix the error, exit vim, re-compile and rinse and repeat. Taught me the paradigm of thinking hard about the problem before starting to code and I think that has helped a lot. This was still better than the punch-card days I have heard but I personally never had the experience.
