If the models are random then we shouldn't be trusting them to do anything, let alone serious applications. If any other type of software told us that it's based on partially random results we'd say "get that shit out of here, I want my software to work first time, every time".
"Statistically good enough" works for some applications but not for others. If a LLM finds a formula that has an 80% chance to be the cure for cancer or a new magical fuel or some amazing new material that's cool, we're not going to look the gift horse in the mouth.
But using LLM to polute the web with advertising texts that are barely inteligible, and using it as a pretext to break copyright in the process, who does that help? So far the only readily available commercial application for LLMs has been to spit out semi-nonsense so that a bunch of bottom-crawling parasitic industries can be enabled to keep on pinching pennies and shitting up everything they touch.
Which, ironically, it will help them to hit bottom all the faster, so in a strange way it's a positive return, but the problem is they're going to take down a lot of useful things with them.
