Meh, I feel the opposite. Even though I come from a culture that values separation of work and free time a lot (France), I still feel like it's copium. The fact is, if you spend most of your valuable brain time on a task, your brain starts to get shaped for such task, therefore I don't see why you can't identify yourself as your job. The stuff the author talks about, empathy, ability to joke etc. is also heavily influenced by your day-to-day activity, your job. Heck, there are even some people who claim they became aphantasic and lost all capacity for dreams and creativity after working too much with computers.

Anyways, I get the point of the post, capitalism sucks and makes most of our existence as worth as cattle, that is, if we don't value the stuff outside work.
