I just built my own version because I was curious how this would look like in a server-side rendered framework like LiveView. But I'm all for it that we build different versions in different stacks and compare notes :)

I’d like to see it go exponential: “one million websites of one million checkboxes”

Perhaps every checkbox in the toplevel site spawns a new, million-checkbox page? :)

If there were to be an arms race like that, my first attempt would be infinite-checkboxes or similar. Would probably run absolutely horribly on anything but the beefiest machines, and cost thousands of dollars for bandwidth.

Would need to come up with a way to make (un)checking computationally expensive to stop the state immediately ballooning to gigabytes in size.

We could call it More's Law.

I’ll setup a chessboard to keep track of them on.
