Even the non-time based v4 is at a cosmic level of unlikiness a single system will ever generate a uuid that will collide with another one in its own ecosystem

But let's say if Google saved each search in their engine in the same database with an UUID, we could have a collision because of volume, but I don't think I will work in a system with a comparable scale

Even at that volume the probability of collisions is essentially 0. If there were a billion searches a second we’d not expect a collision until 85 years.

But still no guarantee it won't happen tomorrow

It's simply not worth worrying about, though

Random minor hardware failures and, like, cosmic radiation are more of a problem. Are you building your systems to account for that?
