Digital art platform CIRCA (short for Cultural Institute of Radical Contemporary Arts) has launched a new exhibition for 2024, part of their takeover of the iconic Piccadilly Circus screen. And they’re going back to their roots, with Ai Weiwei – their first collaborator – on the project. Across 81 days, Ai will pose 81 questions which will be displayed on the expansive screen for two minutes, starting at 8.24pm (or 20:24, geddit?), asking everything from ‘Is Edward Snowden guilty?’ to ‘Do plants have feelings?’. The questions are directed to a generalised ‘AI’ – hence the show’s name, Ai vs AI – in “both an endeavour to reinvigorate the ancient convention of philosophical dialogues (from Socrates to The Enlightenment Salon) and a hand-drawn map of Ai’s own mind”. You’ll be able to catch the artwork until the end of March, but if you can’t get down to Piccadilly Circus to see it in person, it’s also being streamed each night on the CIRCA website.
