I have a similar experience. I was a devoted PhD student working long hours taking on a lot of responsibility. It burned me out, hurting my productivity. I have mixed feelings about it; I love the friends I made and the things I learned, but I don’t think I should have had to suffer what I suffered. Simultaneously I’m somewhat glad I experienced it then, because now I work in tech and I’ll _never_ work outside of business hours (I’ll hack on personal projects I consider fun if I feel like it). And I’m more productive than my colleagues that do. There’s something mysterious about the contemporary PhD, not all good and not all bad.

As someone graduating from undergrad soon, and a intense and passionate person in CS, all of these reasons are seriously making me reconsider the idea of doing a PhD.

I've done the 36-hour straight work grinds, and working from 10 pm to 6 am for multiple days a week. However, I'm tired of doing that, and I've experienced enough burnout already. I'm also not okay with doing highly skilled work for more than 40 hours a week for pay that is almost demeaning—in the range of 35-45k a year. I'm more okay with it at a startup because at least the pay isn't THAT bad at more established ones with multiple rounds of funding. Just like the author, I have people in my life I'd rather devote time to because they bring be happiness. I'd like to have the savings to do practical and important things, such as do on vacation (which I find immensely good for my mental health), buy things for my other hobbies, and buy a house and have enough money to raise kids.

At least in Switzerland, I've heard your coworkers look down on your for NOT taking breaks and leaving at 5. The stipends are a bit nicer. Maybe it's worth it there. Maybe it's worth it anyway because the lack of CS jobs now will translate to requiring a PhD in the future. Maybe I should go through the extended hazing ritual known as a PhD because a startup's work won't be as technically rewarding as a PhD (the only person I know who wanted to do a PhD is now at a startup).

I still don't think the way we want people to work like this is okay. Sometimes I am a 996, but I sure don't want to be one when I need an extrinsic voice screaming into my ear to keep going because I'm not allowed to take a break.

I didn't show up on the first Saturday when I started my Ph.D. program. Next Monday, a professor from _another_ department stopped by my desk to tell me that assistant professors and Ph.D. students are expected to be there at least six days a week. Then he gave examples of a few professors who were there even on Sundays despite being tenured.

Tbh, I was so poorly paid that going to the university on Saturdays wasn't so bad as they had better air conditioning and heating compared to my apartment!

What students get from the deal is literally the hours they put into it. It's completely different from work.

It is still bad, though. The lab should impose maximum hours, because it does nobody any good if you get out of it burned out.
