No, Jupyter is not an app for writing reports and it's definitely not its primary use across DS. When it may take 5 minutes to simply load the data, you can no longer rerun some Python scripts to mess around and experiment with stuff. You need that kernel with data and everything else to have 100% uptime. Similarly, you may want your temporary experiment results that may have taken a while to compute to stay within the kernel even if you're already working on something else. That, plus an ease of inline visualisation, displaying tables and all that.
