There’s one good use case for me: produce a bigload of trialcontent in no time for load testing new stuff. “Make 2000 yada yada with column x and z …”. Keeps testing fun and varied while lots of testdata and that it’s all nonsense doesn’t matter.
I’ve found that testing code or formulas with LLM is a 50/50 now. Very often replying “use function blabla() and such snd so” very detailed instructions while this suggested function just doesn’t exist at all in certain language asked for… it’s still something I’ld try if I’m very stuck tho, never know.
