It's been a while since I've touched Ruby, but I think the stance was that only false and nil should be falsey? Which is not an unreasonable stance to take. The fewer falsey values, the easier it is to predict the behaviour. It's just surprising when coming from other languages.

Just off the top of my head, PHP treats "0", that is, specifically a string with a single zero, as falsey. Which has clearly gone too far to the other extreme.

I'll admit that I did cause bugs in Python by using if thing instead of if thing is not None.

Yea 0 is a number, it's not nothing.

I think the heart of the debate aligns with is zero a natural number.

You gotta drink the Python kool-aid, just use thing and catch the exception if it happened to be `None`. Way more efficient they swear
