Thanks for the comments. I'm the original creator of marimo.

Habitually running restart and run all works okay for very lightweight notebooks, but it's a habit you need to develop, and I believe our tools should work by default. It doesn't work at all for entire categories of work, where computation is heavy and the cost of a bug is high.

From the blog, you will see that reactive execution not only minimizes hidden state, it also enables rapid data exploration (far more rapid than a traditional notebook), reuse as data apps, reuse as scripts, a far more intelligent module autoreloader, and much more.

marimo is not just another Jupyter extension, it's a new kind of notebook. While it may not be for you, marimo has been open source for over a year and has strong traction at many companies and universities, including by many who you may not view to be "real devs". The question of whether marimo will catch on has already been resolved :)

I would consider replacing my jupyterlab usage with marimo were it less opinionated about workflow - it offers a lot of benefits that aren't tied to its execution model. I like the editor/interface and the representation as python files for portability, version control, and the ability to import from other notebooks, but I have no interest in changing my workflow (in particular insofar as marimo is restricted compared to python itself). E.g., I want to be able to redefine variables and use star imports in my personal, exploratory notebooks, and I'm happy to retain responsibility for top-to-bottom executability (as in regular python scripts). I would definitely consider marimo if these restrictions could be opted out of if one has reactive execution disabled.

Thanks for the feedback. We decided early on against having a “non-reactive” mode. It would negate many of our core benefits (including importing from other notebooks), and it would also lead to a fragmented ecosystem — if someone shared a notebook with you, your experience with it would depend on whether it was executed in “reactive” or “non-reactive” mode. Still I appreciate the kind words about our editor and file format, and am sorry we can’t accommodate your use case.
