I think this is the interesting point though. Many people want to use Jupyter notebooks so that it looks reproducible. Not to make it actually reproducible. God forbid it actually has to be re-ran, it could have different results!

I think that's my main notebook gripe: they make it look like if you run the code you'll get these results, but that's not even close to the case. Many people abuse this. At this point, I pretty much assume anything in a Jupyter notebook isn't reproducible.

Yes. A Jupyter notebook is only reproducible in my opinion if you can hit "Restart Kernell and execute all cells" and get the same result.

Otherwise, it should never been shared with other people or even contain relevant analysis you may need for yourself later.

But this is not enough - also the library dependencies need to be fixed. Pluto will make this very easy in the near-future: https://github.com/fonsp/Pluto.jl/pull/844
