finally there is a lot more to a project support than just the language. If you just handed me a ne w module written in a uniq language: can anyone else reasonable CodeReview it if they have never seen it before ? Do we support proxing the upsteam dependency trees into our corporate environment ( aka does it integrate with our build tools yet)? Does our static code analysis software support that language yet? Do I want to support it when the hotShit programmer moves on from this not-good-enough job in 9 months ?

For that last 7 years I've worked at companies from 30-50K employees. All using Google Docs.

Also machine learning people use jupyter, if you think excel can do what machine learning / data scientists need, you don't know what you are talking about.
