This is when any tech person worth their salt should lean over and say:

"Okay boss, we _could_ do that, but so you know what that would mean?"

And then you tell them about cosmic rays, bitflips and redundant computing and what that would mean for the cost of IT at your company.

"... or, we could just use UUIDs like nearly everybody else. I will spend a few days thinking about what would happen in case of a UUID collision and create a mechanism that adverts the worst consequences if you want. That should be enough in my judgement, we could also ask $collegue what if they agree with that conclusion"

On a side note: bosses who think they just need to be convincing enough in order to change physics are the worst. Some bosses expect NASA-level solutions for no or minor resource cost at all.
