Another is that it looks like runme is written in Go instead of python. It's a single executable I can drop onto any new machine instead of futzing around getting a particular python version installed before doing any work.

You nailed it, thanks for calling that connection out. We were very much inspired by literate programming.

This! ipynb files are a nightmare to deal with. Fortunately, you can use jupyter without ever seeing a .ipynb file, by storing your notebooks in a different format (e.g. as programs or as markdown files). Bonus points: you'll hear fewer complains from your local graybeards if they can edit and run notebooks from their favorite text editor.

Ok, so from the front page I got the impression it was only bash. I'm hitting cloud APIs via python so Jupyter works for that, and I'm using the python to ssh into systems and run bash there. The two missing things from Jupyter are 1. ssh-ing to remote hosts and running shell scripts (we do it with a bunch of code) and 2. running cells concurrently. But python is a hard requirement.
