Life After X [Window System]
Jonathan Corbet (via Reddit):
But things have changed in the 25 years or so since work began on X. Back in 1985, Unix systems did not support shared libraries; if the user ran two applications linked to the same library, there would be two copies of that library in memory, which was a scarce resource in those days. So it made a lot of sense to put graphics code into a central server (X), where it could be shared among applications. We no longer need to do things that way; our systems have gotten much better at sharing code which appears in different address spaces.
