Every second, millions of "unique" identifiers are generated across the internet. UUIDs, transaction IDs, session tokens, blockchain hashes... all consuming precious entropy from our universe's finite pool of randomness.

What if REUSING identifiers could save the planet AND prevent the heat death of the universe?

NOT A UNIQUE ID is here to challenge the status quo. We recycle identifiers that are already in use somewhere on the internet. Sure, it might cause a few database collisions. Maybe some authentication systems will get confused. Perhaps reality itself will experience minor glitches.

But think of the ENTROPY WE'RE SAVING!

It's good to know that someone is thinking about first principles, and acting on it.
