Some abstractions leak more than others though, and I don’t think that has that much to do with the level at which the abstraction is. ORM-mappers are very leaky and you have to regularly read what SQL they generate and sometimes even read their source code. Most programmers will never have to read assembly generated by compilers and even less compiler source code.
Yeah you don't have to read assembly. But a higher level abstraction of a non-compiled language like python. The leakage occurs and is shown through performance.
