“Watch this famous video” is not a great response. Many of us watched it years ago and seem to have interpreted it rather differently.

Then you interpreted it incorrectly. I'm not inclined to teach you via HN about a subject that's well documented by resources I've already linked.

I suppose if you mutate them. But we have a linter in place and a CI system that enforces it that prevents that.

There are many solutions, certainly. A network is one option, which I personally prefer, but as I said elsewhere it's a "choose the right tool for the job" kind of situation.
