The feature of being easier to write than assembly is often seen as the biggest advantage of high-level programming languages. The other benefit that comes with them is portability. With high-level languages, algorithms can be developed independently from the underlying hardware. This allows software to live on once the hardware becomes obsolete.
The compiler was a concept that was met with resistance when it was first introduced. This was at a time when computers were custom-built machines bearing individual names like ENIAC, UNIVAC and Mark I. A time when the global demand for computers was estimated to be around five units by the CEO of IBM. In this scenario, it took a visionary to foresee a future where the number of computers would outgrow the number of programmers and hardware would evolve so much faster than software that a compiler would make sense. One visionary was [Grace Hopper].
