Meta has been updating its ad-buying products with AI tools to boost earnings growth. It has also been introducing more AI features on its social media platforms such as chat assistants.

The firm said it now expected to spend between $35bn and $40bn, (£28bn-32bn) in 2024, up from an earlier prediction of $30-$37bn. Is the use of AI a good idea ?
