The really annoying thing is, the people behind AI surely ought to know all this already. I remember just a few years ago when DALL-E mini came out, and they'd purposefully not trained it on pictures of human faces so you couldn't use it to generate pictures of human faces -- they'd come out all garbled. What's changed isn't that they don't know this stuff -- it's that the temptation of money means they don't care anymore
Even with good data, it doesn't really work. Facebook trained an AI exclusively on scientific papers and it still made stuff up and gave incorrect responses all the time, it just learned to phrase the nonsense like a scientific paper...
For real though, we must have reached Peak Ad at some point, or at least we're deep into the realm of diminishing returns. This can't go on forever, right? I mean there's a finite number of things that need to be advertised and a finite number of people with a finite amount of time and patience to look at ads. How long until it all collapses?
