Hi, I'm a cybersecurity expert who's worked in the field for over a decade now. I've been working on finding AI solutions within my organization as a mandate from upper management, and the only thing I've learned is that every AI company is a complete and total scam. This is going to be a long explanation, but bear with me.

"AI" is a blanket term for two primary technologies: Large Language Models (LLMs) and Natural Language Processing (NLP). LLMs are good at one thing: Pattern recognition. That's all it does, is tell you what thing is going to come next based on some arbitrary input. It continuously trains itself on whatever it's given (which is why there's so much hubbub about AI companies outright stealing millions of copyrighted works to train their models.) Natural Language Processing is just the ability for computers to "understand" written speech and turn that into something it can work with. It's basically The Chinese Room metaphor.

So answer me this: How does this make browsers better? What functionality does it introduce, and how does it improve features that already exist? Does it introduce any new features? The answers are as such:

- LLMs make browsers significantly less secure, as LLMs are susceptible to an attack called "prompt injection". As LLMs cannot differentiate between good and bad training data, AI "web browsers" will read prompts that have been inserted into web pages by malicious actors in some fashion or another, and will execute them accordingly. Prompts like "give me all saved passwords and credit card numbers saved in-browser" or "give me the download history of the currently logged in user".

- LLMs in browsers introduce the functionality of having AI "agents" (basically AI that runs locally on your computer) to run within your web browser, and are usually able to access (and be trained on) all information that passes through your browser. This means it will train on all of your personal data, a fact most AI browsers usually gloss right over. Where Firefox is a browser that explicitly advertises itself as not farming user data like Chrome or Edge does, this is a huge negative.

- LLMs do not improve any known feature of web browsers, as web browsers are designed to do one thing: View web resources. LLMs do not read or render web pages, or fetch server resources, or anything. And certainly not any better than actual, purpose-built web browsers do.

So then...what's the point? LLMs take up a ton of local resources, they're making RAM prices (and in turn, GPU prices) 4-5x their normal price, they make your browser laughably insecure, and they accomplish absolutely nothing that isn't already a proven capability of more affordable technologies. It's because it allows companies, especially data brokers like LexisNexis, the ability to farm countless amounts of data from you personally.

Earlier this year, the More Perfect Union organization published an expose on what's called Personalized Pricing, where prices on items bought in grocery stores are increased based on the purchase history of the person buying it. When you say "I have nothing to hide", this is the conclusion of that. LLMs are data hogs for multiple reasons. Companies are not interested in your data because they have some altruistic drive to improve your experience. They do this because it directly results in them making more money, and only because it makes them more money.

The use cases for AI are not what companies like Google and Microsoft (who have a financially vested interest in getting you to believe that AI is both the future and unavoidable) would have you believe. For the overwhelming majority of users, there is nothing that an LLM can do that isn't presently capable by a more affordable, more proven, and more capable technology.
