we should avoid abstractions which permanately hide details, and instead, seek out those which allow us to ignore the details when convenience allows, but promptly think through the abstraction when necessary. Why do you suppose such abstractions exist and that the same abstraction is of as much value to someone else? Given the sheer amount of details on different levels, is it even feasible for someone to be aware of all relevant details? If not, no abstractions that allow you to 'see through them' can possibly exist, because there is no underlying detail for you too see.
