I was curious about this, and I joined a dev shop few years ago, I use a very crappy handmade emacs setup doing mainstream fullstack dev, and I don't envy vscode. A good vscode setup will make some things easy but you're still so far away from helping yourself. Meanwhile I needed to change something to ease my day (parsing some file and correlated with tests) and it was a few elisp lines away. I can reuse magit transient even so I have a contextual menu. And I'm a mediocre emacs hacker... a good one will fly at mach speed. Meanwhile my colleagues are clicking and doing things manually and slowly in their pro IDE.
