Why work ten hours a day if the computer is doing the work?
Sure pal. All jobs are totally important and not at all pointless, wasteful make-work.
lot of performative but in practice half of the job is looking busy.
to paraphrase Cat Power: we could all be free... maybe not.
A horse can't do 70mph for 600 miles between feeds. A horse can travel across obstacles that a car would find impossible.
It's horses for courses and a mangled analogy.
If a computer is doing the grunt work, the person should be used to make the best decisions possible. That can't be done while exhausted because you're working ten hours a day.
Queue up longer term work at the end of the medium-length day and go home/log off.
