"Maybe that's fun if you don't have anything better to do, but when you're actually trying to accomplish something it can be deadly." Doesn't that also apply to, eg.: reading Structure and Interpretation of Computer Programs? Surely, when you're doing a startup, it's a waste of time, but at any other moment, it is worthwhile. I find that reading arguments about these simple problems is not fun, but it's sometimes highly enligthening. If there are hard technical reasons for preferring A over B, I would like to know.
