Jose's reply suggests the basics have Elixir equivalents. I can't really speak to that side but I can say the usability story is much much better.

The last time I gave Jupyter notebooks a go it was a full session of installing and updating various Python tools: pip, conda, jupyter then struggling with Python versions. You end up piecing together your own bespoke setup based on other people's outdated bespoke setups you find while searching for your error messages. Maybe that's better now, this was a few years ago. For Livebook it's "download the app and run it." Other options exist and are well documented and straight forward. I set up a livebook server on our k8s dev cluster with a pretty simple Deployment I wrote just from looking at the livebook README notes on docker. We've made livebooks that connect to the elixir app running in a different namespace on the cluster. Very cool.

Once you have Livebook going the `.livemd` file is both version control friendly AND very readable markdown file rather than the big json objects used in `.ipynb`.

For Livebook rebuilding cells is a lot more repeatable. It also does a good job of determining if a cell re-execution is necessary or not if a previous cell is modified which can save you a lot of time. Likewise the dependencies installed are captured at the top so I've never had a problem when sharing a livebook. The other person always gets the same results that I had. I don't remember how it worked for Jupyter but it's really cool to collaborate with someone by both going to the same notebook session. It's like working on the same Google Doc but you are writing and executing code.

Now with the Publish functionality I can see using a livebook to throw together some functionality and share it with non-technical users in your org, while having it backed up to git for posterity.

I avoided Smart Cells for a while because I didn't like the "magic-ness" of the UI hiding what the code was doing, but as Jose has shown in the launch videos this week you can easily see the code they are backed with and replace the cell with the code if you want to take full control. Maybe it was always like that but I didn't realize it at first. They really make setting up stuff very easy without limiting you later on.
