How unique us GUID

128-bits is large enough and also the generation algorithmic rule is exclusive enough that if 1,000,000,000 GUIDs per second were generated for one year the chance of a replica would be the only 500th. Or if every human on Earth generated 600,000,000 GUIDs there would solely be a 500th chance of a replica.
