I don't see that the age of the practice means we have to arbitrarily change it. On the other hand, I have two concerns: - on the weeks where I took Friday off for travelling, I did not complete as much work as on a normal week. The output was smaller, and I had to squeeze more things into the four days which was just excruciating. - I read about a poll in my home country where 74% of people said they will never work again if they had enough money, and only 16% said they will never quit their job even if they're rich. So perhaps ideas like 4 day work week and UBI works for those 16%, but not for the majority?
