The prospect of a world without work - that was the vision offered up by Elon Musk this month. The US tech billionaire has predicted that artificial intelligence will eventually mean that no one will have to work. Mr Musk suggested that society could reach a point where “no job is needed” and “you can do a job if you want a job, but the AI will do everything”. Contrasting with the idea of the zero-hour working week, Indian software billionaire and Infosys founder NR Narayana Murthy - says that young people should be ready to work 70 hours a week to help the country's development. Since the pandemic, many companies allow their employees to work from home. Others have moved to a four-day working week, citing benefits such as increased productivity and significant financial savings for employees on transport and childcare. But some employers insist the shorter working week doesn’t work - saying employees ended up having more stressful workdays, and feeling exhausted once they reached their scheduled days off. How many hours should a person work in a week? Is a world without work desirable? If AI will be capable of doing many jobs, should employees be fearing the future - or take advantage of these changes, and strive for new ways of working? What’s the future of work?
