One of the funniest parts of the LLM wave is discovering that cron was so annoying to use that we will burn the planet to put an interface on it that people can actually work with.
The tendency for absolute inefficiency is effectively unbounded until scarcity is imposed.
Assuming you are referring to using an LLM to generate crontab entries, is that a bad move? Seems like it removes the need for layers of UI that most of the time is never used. Same goes for regexes. Actually same for SQL. No need for layers to translate between what the user can specify and what's executed. Just type what you want to query for and the LLM generates the SQL.
