In San Francisco, technology companies are now spending billions on a new way to use artificial intelligence (AI). This change happens because traditional data centres, which usually process AI, are now facing problems. These problems include not enough special computer parts and higher electricity costs, so companies want to use 'edge' devices such as smartphones and home computers instead.

The main reason for this change is that using edge devices helps companies save money and work faster. When AI runs directly on a local device, it does not need to send information back and forth to a big data centre. This makes AI services quicker and cheaper to use.

Because of this shift, new types of computer chips are now being put into laptops and phones. Experts say soon, much more AI work will happen on people’s own devices rather than in faraway data centres.
