For sporting events, for example, the alternative to prediction markets 5-10 years ago was to use a website where you bet against the house directly, and they'd usually take around a 15-20% spread, and they'd ban you and keep your account funds if they decided you're winning too much. Now you can bet on the same events on prediction market sites, with around a 1-5% spread, and the house doesn't care how much you win (so there's actually an argument that you're playing a game of skill, compared to the old format where you definitely weren't, since you'd be banned for being too skilled).

That's how a trope starts. When a minority of writers are using a particular pattern, it's personalized style. When a majority of writers in a genre adopt the same personalized style, it's a trope.

We find AI tropes especially annoying because there are three frontier LLMs producing a sizable chunk of text we read (maybe even a majority of text, for some people) lately. It would also be annoying if a clique of three humans were producing most of the text we read; we'd start to find their personal styles annoying and overdone. Even before LLMs, that was a thing that happened in some "slop" fiction genres where a particularly active author would churn out dozens of novels per year in one style (often via ghostwriters, but still with a single style and repetitive plot pattern).

How does that make it different? More features could always be added to most buildings. You could keep adding rooms onto the side, update the floors/ceilings/walls every year to stay trendy, add a water feature, expand the basement with a tunnel network, etc.

There was a period of ~1000 years where you could also make this argument against some high-minded guy advocating for democracy.
