> A UUID is a collection of random characters like f81d4fae-7dec-11d0-a765-00a0c91e6bf6 This statement is just wrong. More accurately, A UUID -can be- a 128 bit number made up of mostly random bits (UUIDv4) which can be represented as a string using a common representation. Sure, that may well be a common case for most, but there are very completely non-random UUID versions as well, such as UUIDv1 or, more recently, the somewhat random UUIDv7. The author's proposed ID system is less defensible against some of the other UUID versions which aren't addressed. But that initial description suggests that the author doesn't have a complete enough understanding of UUIDs to really make a credible case about UUID problems (which do exist) vs. their own proposed system.
