I'm not clear how this is different from scammers targeting humans? If anything, I'd expect it to be easier to set up the LLM agent to have secure/cryptographical validation of the providers, to prevent against the sorts of traps that humans fall into.

In the simplest case, we could just have trusted authorities provide lists of verified booking partners, same as e.g. Google Flights does now.

That would be the first step of rollout. The next step would be to ask you in ways that make it hard for you to say no. An LLM agent isn't going to stop companies from bad behavior/dark patterns, it's going to make them more effective at deploying dark patterns to segments of the market.

I think only competition and/or regulation helps push down the allure that dark patterns present to companies.

For the average desktop user, Linux never had anything to offer over Windows. The last nail in the coffin was obvious to me at the time: Linux didn't make any headway when Microsoft started shoving the first ridiculously-bad versions of Windows 10 down everybody's throat by abusing a security update channel. At that point it became clear that there was simply no demand for Linux in the desktop market except at a niche hobbyist level. Stockholm Syndrome was in full effect among Windows users, and it still is, and, well, I guess that's just the way it goes.

The enshittification of the Internet is even worse, though. I think personalized search and content curation through the use of local AI agents may be the only way to buck that trend.

I want something that will do for companies like Google, Amazon, and the news media what SpamBayes did for email: make it useful again. Local filtering by a tireless and incorruptible proxy whose interests are aligned with my own is the only way forward IMHO. The only question is how long it will take. My rather-useless guess is more than a year, less than ten years.
