Built on copyright infringement, not plagarism (the data scientists that built them aren't going around pretending all the training content was their ideation/creation). There are so many NLP tasks and areas of research that have been wholly obsoleted due to LLMs including sentiment analysis, summarization, translation, NER, data extraction, etc., so I find the "no known use case" to be rather ignorant. The first consumer computers also had tremendous costs. Paradigm shifts in technology are never cheap until scaling.

I think this comment is unfair toward @cubism_pitta@lemmy.world and you should reflect a bit on why that is.
