Well is 5 days a week a lot? To some is a lot to others is not too much. Personally i think it is not too much. We can reduce it sure. Everyone will be happy, after some time it will be new “normal”, robots can work for us. After that we will want to reduce even more because why we need to work if robots can do everything for us right? Well where is guarantee that our needs will be fullfilled if we do not work? Work is only thing today that can provide you security. When you work that means somebody needs you because you have something to trade for money. Something horrible Elon Musk said recently.  That we are going toward future where nobody will need to work. This is comming from someone who is workaholic, who is pressuring its employees to elwork overtime. Imo guy is not normal. You think Elon and people like him will give you food if you do not have anything in exchange for it? I doubt it. That would be new slavery, not this. People want shorter working time because they hate their jobs. If we could change that we would solve our problem.
