Also a scientist here. The part of this article I disagree with is "Science is a profession, not a religious vocation, and does not justify an oath of poverty or celibacy".

I really think it is the closest thing I have to a religion. It alters how I see the world, defines the way I think about how to approach problems, and consumes every waking moment of my life.

Of course, I've had many failed relationships either directly or indirectly for my career, and it has taken my health (I sustained a spinal injury at work) and best years of my life. I feel deeply uncomfortable when I am _not_ working and it is difficult for me to relax. Intellectually I recognise that it is deeply unhealthy but every time I write a grant everyone else in the world who applies is ranked and objectively compared to me -- and I can't shake this feeling that _they don't sleep_, so why should I? It's an absolute obsession and I go into this hyper-focussed mode when I _actually_ get things done and, when an experiment reveals something for the first time in the world, the feeling is amazing.

I've just won an academic prize and have a tenured post. I'm deeply, deeply insecure and have a very unhealthy relationship with work. Many academics I know – especially in medicine – are likely diagnosable with very real conditions...

Sounds like you’re describing how things are, while the author is describing how things are ought to be. It’s fine to be obsessed and sacrifice the rest of your life for a job if that’s your choice. If that’s the only option to succeed, however, you severely limit the pool of people who are willing to make that sacrifice, and (I believe) slow down the inflow of ideas and creativity that push science forward.

Is it not? I'd assumed that the dramatic increase in people with doctorates was simply a mix of the new era of practically unlimited student loans, university being quite enjoyable, and a desire to avoid entering into the 'real world.' It's not like people are planning to become academics, but by the time somebody completes a doctorate in e.g. sociology, they're gonna be buried in a mountain of debt with relatively few career options.

Most doctorates are funded, at least in the sciences. There are certainly some people who go to grad school because it seems like the logical next step but they tend not to complete a PhD.
