Cheap snark aside, what I think happened is:
Lots of cool new innovation happened in the 1980s-1990s (mostly around reinventing everything that mainframes had already done for decades, but on small cheap affordable systems by and for people who'd never used or programmed mainframes)
But the innovation itself meant the only way of making those systems talk to each other was through APIs invented in the 1960s:
* Unix's hierarchical filesystem
* TCP/IP's packets and streams
