Reviewer scorecard
“At $500/mo it needs to replace at least 10 hours of developer time per month. In my testing, I spent more time reviewing and fixing its output than I saved. Not there yet.”
“Reactive execution eliminates the biggest Jupyter pain point — hidden state. Cells re-run when dependencies change.”
“The marketing writes checks the product can't cash. 'Autonomous software engineer' implies reliability that doesn't exist. It's a talented intern that needs constant supervision.”
“Finally, a Python notebook that doesn't produce unreproducible results. The reactive model is correct.”
“Devin is early but directionally correct. The autonomous agent approach will win eventually. Cognition has the best shot at getting there first. Invest in the future, not the present.”
“Marimo proves that notebooks can be reproducible. The deployment as web apps extends their utility.”
