Google says a new AI tool on its search engine will rejuvenate the internet. Others predict an apocalypse for websites. One thing is clear: the current chapter of online history is careening towards its end. Welcome to the "machine web".
The web is built on a simple bargain – websites let search engines like Google slurp up their content, free of charge, and Google Search sends people to websites in exchange, where they buy things and look at adverts. That's how most sites make money.
An estimated 68% of internet activity starts on search engines and about 90% of searches happen on Google. If the internet is a garden, Google is the Sun that lets the flowers grow.
This arrangement held strong for decades, but a seemingly minor change has some convinced that the system is crumbling. You'll soon see a new AI tool on Google Search. You may find it very useful. But if critics' predictions come true, it will also have seismic consequences for the internet. They paint a picture where quality information could grow scarcer online and large numbers of people might lose their jobs. Optimists say instead this could improve the web's business model and expand opportunities to find great content. But, for better or worse, your digital experiences may never be the same again.
On 20 May 2025, Google's chief executive Sundar Pichai walked on stage at the company's annual developer conference. It's been a year since the launch of AI Overviews, the AI-generated responses you've probably seen at the top of Google Search results. Now, Pichai said, Google is going further. "For those who want an end-to-end AI Search experience, we are introducing an all-new AI Mode," he said. "It's a total reimagining of Search."
You might be sceptical after years of AI hype, but this, for once, is the real deal.
