A new crypto firm wants to scan your eyeballs – should you look away?

Worldcoin wants to prove I am "actually human". At least that is the explanation a staff member gives for a cryptocurrency venture scanning my eyeball in a London office building. Without the optical scan, Worldcoin will not verify your "humanness" – you could be a robot and you won't get any crypto. Welcome to financial security in the age of artificial intelligence. Concerns have been voiced about the privacy implications of Worldcoin, which was co-founded by Sam Altman, the chief executive of the ChatGPT developer OpenAI.
