I used Jupyter Notebook before it was popular and back when I was a PhD student. I pushed in a few places for the unorthodox way of exploring data in a browser. Now, I am back - but only thanks to wonderful code editors and their good support of Jupyter Notebooks. I recommend VSC (or, this year, Cursor) as the default environment for data sci.
That's a cool blogpost! I'm mostly using Cursor now (just waiting until someone makes a kick-ass Emacs package so I can switch back!) so I can definitely see your perspective.
I'd be curious to hear a bit more about the kind of work you do that made you switch. Also if there's anything you miss in VSC/Cursor vs Jupyter. If you don't mind a small email exchange, let me know and I'll drop you a message :)
