PDF's ubiquity is 100% that it printed the same (or close to same) on any postscript compatible printer. It's tech so old many in the industry ignore the reason it existed (and still exists). Every solution beyond PDF has also been either closed source (read Microsoft) or ignored. It's useful, that's why it exists. Yes, it's archaic, yes, it's hard to read for tech people, but for non tech people, it solves an issue that plagues the entire software industry: Standardization.
