I like IDs I can read out over a call, or recognize when I spot them in a log file. The few times I've used UUIDs for IDs I've later regretted it.

“14632” in a log file could be anything, whereas a UUID is way more explicit and searchable.
I have frequently memorized IDs of things in systems I interact with often:
"Oh, it's user 14632 - yeah I've seen that ID crop up against this issue a bunch of times in the past"
I can't do that with UUIDs.
Sure, but I think you would usually optimize for the inverse - actively finding a needle in a haystack rather than passively hoping a needle falls in your lap. I get 1k hits for "14632" in our Splunk for the last 60 minutes, all of it rubbish. Durations, image sizes, worker IDs, primary keys, port numbers.
Search for a UUID and the results are guaranteed to always be relevant. Can't do that with integers.
