This is akin to reviewing how well a screwdriver drives nails. Yes, it has problems. That doesn't mean it's a bad tool - you're just not using it right. Does it require discipline? Yes, but so does the screwdriver. That being said, I think jupyter specifically has some legacy issues around format, and I prefer R markdown. As much as I love pycharm, it's never going to do more than replicate the notebook experience. IMHO, the main author publishes on code UI/UX, the title seems more like click bait. Not sure why it's so upvoted.
