good lord, now we have LLM-speak "footguns" in article titles. what have we come to.

what about the load bearing real unlocks of the footguns?!??!?

? Footguns as a synonym for "caveat" or "gotcha" were in use long before LLMs. I hate Claude speak too but there's no need to knee-jerk blame everything on LLMs.

walrus01•8m ago

While that is true (the LLMs surely had to learn it from pre-existing content), I think it's been so thoroughly overused and turned into a cliche that the term has been ruined for the foreseeable future.

Felk•5m ago

I think most of the confusuion comes from "AT TIME ZONE" being the syntax for both the conversion from _and_ to timezone'd timestamps. Maybe it would have been more intuitive had the two operations gotten different wordings, e.g.:

timestamp to timestamptz: AS ZONED AT TIME ZONE ...

timestamptz to timestamp: AS LOCAL AT TIME ZONE ...
