Even the “thinking engine” ones are wild to watch in motion, if you ever turn on debugging. It’s like watching someone substitute the autosuggest of your keyboard for what words appear in your head when trying to think through something. It just generates something and then generates again using THAT output (multiple times maybe involved for each step).
I watched one I installed locally for Home Assistant, as a test for various operations, just start repeating itself over and over to nearly everything before it just spat out something completely wrong.
Garbage engines.
Basically reworded what I was saying almost exactly, but yes.
