it’s probably a file on the disk somewhere so try using the find command on / and filter name by *.icc extension. You should spot it from there.

I agree with the sentiment, but a 4 day work week(or 6h/day) won’t help at all, exactly because of this. Most people will just do more passive entertainment consumption in their newly increased freetime instead of informing themselves about some complex issues or learning something new.

And at least where I live, the people that are smart enough to do what you want them to, already make enough money to work however they like and have more than enough free tkme for this kind of stuff. (I personally know some who are well off financially and all they do is <20h per week or freelance 3-5 months per year)
