I don't understand this sentiment at all. The business model writes itself (so to speak). This is the company that perfected the art of serving up micro-targeted ads to people at the moment they are seeking a solution to a problem. Just swap the search box for a chat bot.
For a while they'll keep the ads off to the side, but over time the ads will become harder and harder to distinguish from the chat bot content. One day, they'll dissapear altogether and companies will pay to subtly bias the AI towards their products and services. It will be subtle--undetectable by end users--but easily quantified and monetized by Google.
Companies will also pay to integrate their products and services into Google's agents. When you ask Gemini for a ride, does Uber or Lyft send a car? (Trick question. Waymo does, of course.) When you ask for a pasta bowl, does Grubhub or Doordash fill the order?
When Gemini writes a boutique CRM for your vegan catering service, what service does it use for seamless biometric authentication, for payment processing, for SMS and email marketing? What payroll service does it suggest could be added on in a couple seconds of auto-generated code?
AI allows Google to continue it's existing business model while opening up new, lucrative opportunities.
