LLM's are statistically average by design, if one wants something nice then effort and/or expertise is required. To exaggerate: "A broken clock has the correct time twice a day", that does not mean I will use it.
Even if the output is correct then one could say that the particular case is not slop, but I think that is not the case because the LLM's will never capture our mistakes, biases and emotions. That to me is a no-go in most cases. To me slop is something lazy and soulless, not necessarily correct/incorrect.
As for technical output like programming, to me is also a no-go because these companies do not respect licenses and overall have bad practices. Like monopolizing open knowledge for example.
I'm in fact not technically anti LLM's, Neural Networks are a fantastic piece of technology and LLM's are a fantastic implementation. Advancements like chess engines, image recognition, language translation are the most well known benefits of it. In the end I'm anti whatever these big companies with their debt hiding shit are trying to accomplish.
I hope this answer your question.
