Strong words for somebody who didn't even take a minute to take a look at it. None of this is true. You can, of course, share code between snippets. Let all your code run in a single session, such that later snippets can implicitly use results from previous ones. Just like Jupyter. So, when staying within a single language it runs as a single program. But you can also pass values to and from other languages. Sure, it's not a complete byte-level interface, but it is much more flexible than Jupyter will ever be.

I can only assume the whole "concept of dependent cells" goes out of the window once you start using implicit state? Because if so, then it's no better than Jupyter.

(At best, I guess you could define dependencies manually (and maintain them alongside the code), which is nothing but one more place to inevitably mess up. I'm not sold, not in the slightest.)
