Memes only have impact in aggregate due to emergent properties in a Mcluhanian sense. An individual meme has little to no impact compared to (some) works of art.
its the hype oyher people make for them, fairly typically after the artist has died that makes the impact.
stealing the mona lisa is what gave it its impact, rather than than brush strokes
LLMs and AI art flip this around because potentially very little effort went into making things that potentially take lots of effort to experience and digest. That doesn't inherently mean they're not valuable, but it does mean there's no guarantee that at least one other person out there found it valuable. Even pre-AI it wasn't an iron-clad guarantee of course -- copy-writing, blogspam, and astroturfing existed long before LLMs. But everyone hates those because they prey on the same social contract that LLMs do, except in a smaller scale, and with a lower effort-in:effort-out ratio.
IMO though, while AI enables malicious / selfish / otherwise anti-social behavior at an unprecedented scale, it also enables some pretty cool stuff and new creative potential. Focusing on the tech rather than those using it to harm others is barking up the wrong tree. It's looking for a technical solution to a social problem.
Yep, this is the current understanding that is being hard challenged by LLMs.
It matters because the amount of influence something has on you is directly attributable to the amount of human effort put into it. When that effort is removed so to is the influence. Influence does not exist independently of effort.
All the people yapping about LLM keep fundamentally not grasping that concept. They think that output exists in a pure functional vacuum.
