We'll never stop people wanting to use LLM content - the issue I have is the stuff that is absolute crap, obviously generated, and adds absolutely no value. We already have humans doing a lot of that, we don't need LLMs to do it more efficiently.
eg: The posts that are a person rambling about what a 0.00000007% move in the btc price has to do with the sovereignty of cows in the inner mid-west of the US because some farmer has a BTC mining rig in their back barn, and winter is coming, therefore, they'll gather 'round it for warmth ... and -
LLMs are just tools. People can use them responsibly, or they can circle the drain of their own creations, as people who are "smart enough" will be able to poke holes in the content, or the argument, and know when to not engage.
Having said that, in "good hands" LLMs have the potential to be devastating to people who don't choose to adapt to the rapidly (and incredibly rapidly increasing) tide of technological "innovation" that we will witness over the next few years).
Heck, there may even be an anti LLM renaissance, who knows?!
