I'm pretty excited about this. I'm admit I was skeptical when I saw a similar LiveView based notebook a couple months ago, and wondered why not just make a kernel for Jupyter. But with the idea of real-time collaboration I get it. And with the momentum of Jose and team behind it, I think there's real promise here, especially once they figure out widgets and charts, which they have an open issue for. I program in Elixir at work, so I usually have an iex shell open, but lately I've been using a LiveBook and it's great. And I love the new Mix.install in Elixir 1.12 demonstrated here. Using a hex package in an adhoc way was a real shortcoming in Elixir before. Shows the power of having this thing developed by the language team.
