It's a bit of a lazy take - if we don't work, we don't hang out with other people? Why? Humans are social beings and will hang out for many reasons besides work.
The more interesting question is, if this happens, how will society organize. Would companies subsidize our new bohemian way of life? Why? Would the state need to create incentives for them to focus in the right things? Would there be a need for companies and governments? Would we give up all our autonomy?
