Expenditure is growing fast and consumer take-up accelerating. But alarm bells are sounding

The race is very much on. Elon Musk’s SpaceX, which makes AI models as well as space rockets, announced last week it is seeking a $1.77tn (£1.31tn) valuation on the US stock market while Anthropic, the startup behind the Claude chatbot, said it had filed for an initial public offering. OpenAI, the developer of ChatGPT, is expected to follow.

This latest peak in the AI market comes amid a multitrillion-dollar spending spree on related infrastructure such as datacentres. Meanwhile, companies are attempting to deploy the technology in a way that makes investing in it worthwhile. Here’s a look at what stage the AI boom is at and six key charts that tell us how we got here.

While the technology is set to play a growing role in modern warfare, there remains an unresolved ethical challenge

Should the AI-powered drones of the future have a licence to kill? The question is becoming ever more pressing as governments and the defence industry acknowledge that drone systems will play an increasingly crucial role in future warfare.

With drones being deployed in huge numbers in the Ukraine war and AI being used to assist bombing missions in the Iran conflict, there is an expectation among some observers that weapons will have to operate with increased operational autonomy, which means they will need something approximating a moral framework.
