Fun Fact

The odds of generating the same random GUID twice are so low that you would need to generate billions every second for many years before a collision becomes statistically likely.

Historical Context

GUIDs originated at Microsoft in the 1990s as a way to uniquely identify objects across distributed systems. They are functionally equivalent to UUIDs and today are standardized and widely adopted across operating systems, databases, and programming languages.
