Why are there concerns AI could threaten humanity, and how real are they?

Some AI researchers say there are worrying signs of systems developing in their capabilities and power too quickly.

Evan Hubinger, made headlines with his belief that there is a greater than 10% chance AI "could kill all humans" within the next decade.

He works in alignment, a field which aims to build human ethical ideas and principles into AI. In other words, it aims to keep it on track with what humans value.

While he said the risk from current systems was "low", his comments came as another researcher quit Anthropic and warned those developing the tech were losing their grip on it.

Jacob Coxon told the BBC he and other staff were "genuinely frightened" about the speed of advancements and what it could mean for humanity.

These concerns are the latest in a long line of fears about AI's potential to threaten humanity should it grow to match or surpass human abilities.

Such worries date back decades, with Alan Turing writing in the 1950s that should intelligent machines become possible, they could take control.
