Another analogy which never made sense to me was improving by just 1% every day (1.01³⁶⁵).
Analogies do help explain phenomena I cannot even relate to at all, like telling me how life on Mars would be.
Ofcourse I'm not invited to parties as you can imagine, taking things literally.
A big part of understanding something is getting used to it, and analogies help with getting over a mental hang up. They may also help with deciding which areas of the new space to explore first.
But we should be examining the limits of applicability, as we do for most cognitive tools, so we know when to switch from one tool to another. It also helps to combine such tools in a complementary manner.
