But quantum computing, which has experienced major breakthroughs in recent years, may far surpass the performance of conventional computers on particular tasks. Batley believes this would “allow the development of much more capable AI systems to probe multiple aspects of our lives”. The situation for “big tech” and the countries that are leading in AI can be likened to what game theorists call the “prisoner’s dilemma”. This is a condition where two parties must either decide to work together to solve a problem, or betray each other. They face a tough choice between an event where one party gains – keeping in mind betraying often yields a higher reward – or one with the potential for mutual benefit.
