Edit: All major AI companies have millions if not billions of funding either from VCs or parent companies. You can't start an AI company "in your garage" and be "ramen profitable".
Edit 2: You don't even need to monopolize anything. All major search engines are ad-driven and insert sponsored content above "organic" search results because it's such an obvious way to make money from search. So even if there wasn't a product monopoly, there's still a business model "monopoly". Why would the same pattern not repeat for "sponsored" purchases for agentic shopping?
And who's going to stop that? This government?
Why do we all keep making the same obvious mistakes over and over? Once you are the product, thousands of highly paid experts will spend 40+ hours per week thinking of new ways to covertly exploit you for profit. They will be much better at it than you're giving them credit for.
