Wait until you have to work with clients that don't even have staging environments let alone automated testing. Source control, CI/CD, automated testing, pull requests, code reviews, feature flags, linters, good logging etc. might be the norm on HN but not everywhere, especially companies where tech isn't the focus.
It can also be a tough sell to make process improvements like this when the old way got them this far and they want new features now. I've worked with clients that don't even use source control, do all edits on production and there's no way setup to develop locally.
Although my current day job is very professional about this, I’ve seen the other side, too. «We have some code from 5-10 y back, can you compile it?» and only half the files are there.
It would be great if HN had some content on «moving from random files on a network drive to git and basic automated testing» - it’s not an easy job and others would benefit from such writeups.
