Mentioned in the article's comments:

For those unfamiliar, UUIDv7 has pretty much the same properties – sortable, has timestamp, etc.

ULID: 01ARZ3NDEKTSV4RRFFQ69G5FAV

UUIDv7: 019b04ff-09e3-7abe-907f-d67ef9384f4f

UUID 7 is so much easier than the ULID in the article manipulate. Pretty much every language and database has the string manipulation and from_hex functions to extract the timestamps without any special support function. Whereas a format that is too clever is way more complicated to work with.
