This reminds me of https://www.getguesstimate.com/ , a probabilistic spreadsheet.
The authors of Guesstimate are now working on https://www.squiggle-language.com/
Someone also turned it into the https://github.com/rethinkpriorities/squigglepy python library
Wow, this is fantastic! I did not know about squiggle language, and it's basically what I was trying to get to from my unsure calculator through my next project (https://filiph.github.io/napkin/). Squiggle looks and works much better.
Thanks for the link!
I was looking for this. Seen it (or a similar tool) ages ago.
Want to use it every 3 months or so to pretend that we know what we can squeeze in the roadmap for the quarter.
