This challenge is currently in the process of being closed as 'too-narrow', which in this context means "this challenge is too hard/has too many restrictions, and thus is off-topic".
I don't think we should allow this. Compare to Build a working game of Tetris in Conway's Game of Life. Both are ridiculously hard, but neither have been proven impossible yet.
Do we vote to close challenges because they are too hard?
I'm voting to close this question as off-topic because it's too narrow. This question is less likely to be solved than the one for creating Tetris in CGOL.
which is a far cry fromvoting to close challenges as impossible.
