As computing power has increased over the last few decades, we can have programming languages optimised for humans, not computers. Computers are powerful enough nowadays to allow Ruby methods to be written in clear English, which take longer to process than some terse machine code, but makes for a far more enjoyable coding experience, because Ruby is readable.
Book.all, for example, means “get all the books”.
