But the judge who presided over his 2019 case

"We had a mass casualty incident and that is probably the worst thing I have ever seen in my medical career."It was both scale and the types of injuries involved.

Dr Lennon has been in Gaza for three weeks and is due to return to Derby next week, a prospect he said left him with "mixed feelings"."I'll be a little bit sad to leave the people behind but I will be pleased to get back to my family," he said.

Dr Lennon joined up with UK-Med, a humanitarian medical non-governmental organisation providing aid in conflict and disaster areas, about seven years ago and has treated people in a number of countries.But not everyone has the luxury of opting out of AI.

Jackie Adams (not her real name), who works in digital marketing, resisted AI initially on environmental grounds, and because she thought using it was lazy."I heard about the energy needed to power data centres and the amount of land they take up, and it didn't sit right with me.
