You work as much as your culture and lifestyle dictate.
I work plenty of hours. I work the number of hours I want to work. Now that does indicate to many people that I am a perfectionist, a once esteemed quality, now widely regarded as mental illness, a negative character trait that needs to be eliminated.And that's okay, it makes me a total beast to compete with.
There are plenty of people in the US who work as little as they can, if they do just enough to not get fired, they consider that a win. And that's okay - maybe that makes them happy.
This has nothing to do with AI, it's largely got to do with a culture of not attempting to fuck yourself over to make an extra dollar, something that would be seen as "slack" in the USA. Many people in Europe work to live and do the minimum, not live to work.
Obviously people on low wages unable to make a living don't have that option, but that doesn't describe many people. I see engineers in our USA offices proudly working 60+ hour weeks. Congrats you earn over $200k, do you have any spare time to spend it?
The idea that if you make over 200 K annually means you don't have time to spend it, that you are chained to your desk is a meme, one that I believe is something to salve the lower paid.
I take lots of vacations, I have many expensive hobbies. I eat organic as much as possible. I wear good clothes. Those things cost a good deal of money. So yes, I have plenty of spare time to use that money, despite the memes. I even have time to post on Slashdot!
My advice is that sometimes memes are counterproductive. Perhaps some of the well to do people many revile, don't have an issue with others removing themselves from competition. A paradox? Well, for my part, I try to do the opposite, telling people they might have it in themselves to do better. Which ironically really pisses some off. Telling a person they can do better is counter to the meme that they are being kept down by the man.
