The same could be said about other types of abstractions, such as using a compiler versus assembly. In the vast majority of circumstances, developers get far more accomplished using higher level abstractions and frameworks.

In very extreme circumstances, portions of an application may need to be rewritten at a lower level for optimizations, but that doesn't negate the value provided by abstractions that allow the developer to be more productive expressing higher level concepts while the computer handles the tedium of how those concepts are translated into machine code.
