Reading this, I couldn't help but recall Feynman's quote: "If you think you understand quantum mechanics, you don't understand quantum mechanics." I love cussing and discussing quantum theory / physics / computing. And Feynman is 100% right. https://en.wikiquote.org/wiki/Talk:Richard_Feynman

Currently reading The Undivided Universe (Bohm, Hiley), recommend. More intuition, less "think"ing

Why do you say that?

Because "physics" it builds upon is wrong.

Your vagueness makes it difficult to take your comment seriously. Are you saying quantum mechanics is wrong or are you making a more subtle argument?

I think it's perfectly fine to quit a PhD. It's not for everyone, and not every academic is a good supervisor, and not every phd project is a good one. Some people who even are not great academically and don't have a lot of scientific drive can still do a PhD with a good advisor and project (similarly for someone who has a lot of scientific drive, even a crappy advisor is not a problem).

What however I didn't like in the original post are the sweeping comments about the supervisor's knowledge and research. It is possible that the author is right, but I would be somewhat sceptical, given they come from somebody who just spent 1 year as a PhD candidate.

I would love PhDs to be thought of as something you dive into when you have something to pursue, perhaps many years later in life rather than a follow on immediately after study. As a comparison imagine if VC funding only went to the highest scoring new grads and the business proposal was asked for after the invitation to take on VC funding. That's pretty much what's been happening with PhDs. You get the marks, you g…

PhD is an apprenticeship to do research. If we left it until later in life, we wouldn't have anyone trained to do research.

>we wouldn't have anyone trained to do research

Can you explain this further? I don't follow how, for example, if I wait 10 years to begin a PhD there is somehow no research being conducted.

Even if everyone suddenly waited 10 years, there would only be a lag for the first generation.

> There are way more PhD's then there are research positions Nonsense. Look at how many job openings there are for PhDs - people can't hire them fast enough. I was in a call the other day saying how hard it is to even find PhDs to interview, let alone get them to accept your offer.

There are three types of jobs a PhD could go into: A) industry job (just job to us mortals), B) industrial research lab (a company, but does research. An example would be IBM or Microsoft Research in CS), or C) a professor. For context, I work in a research group in a building full of PhDs, postdocs and professors. For A, PhDs ought never be short of work. They were likely good students, they also spent 3-5 years loo…

As to C, the math is simple. If each tenured professor has tenure for 30 years and has a single phD student graduate every 5 years, statistically the number of tenured professors need to grow by 500% in 30 years (over 6% per year) for all those phD students to get a tenured job.

Now, there are hot topics that may see something around this amount of growth for a while, but many don’t. For example, in biology, genetics and biochemistry may somewhat have that growth rate, but if you’re in any other subfield such as ethology, forget it. If you’re a historian, did research on some ‘obscure’ language such as Middle English, or are working in some corner of mathematics that doesn’t have direct applications, you can forget it, too. If anything, the number of tenureships in those fields is shrinking.

Of course, many tenured professors have a lot more graduating students during their career. In medicine, one a year isn’t uncommon. That would require a field that grows by over 12% each year.

The deceptive thing about this is that, as a phD student, you don’t see those 30 competitors. You’ll only see maybe eight to ten. Some of them graduated a few years before you, others will start after you graduated.

PhD projects are about going and finding out something that’s not known. Adequate supervision is important, but it dries up very quickly if you’re working on something novel. You cannot expect an academic to be on top of the fine details of everything in all of the sub areas of what their PhD students and post docs work on - they’re coordiators more than active researchers normally at that level.

I will hand in my notice tomorrow, after circa 1 year as a PhD student. In fact, I'm switching fields: from a PhD in Mechanical Engineering (energy systems) to a software developer role in a non-engineering sector. Very little of my 7 years (MSc) and subsequent circa 1 year as a PhD will carry over. Certainly an exciting step, although the program here was pretty excellent. Good supervision, full funding for the enti…

Your face when in 5 years you find yourself in project management: >:0

Absolutely possible. The difference might be that PhDs don't conventionally have the 'downward' path available. They have a lower bound to the career roles they can take up. You may well violate that bound and do more 'line worker' type roles, but that'll get funny looks, might actually be harder to get into with the title (some people might even conceal it for such reasons) and the PhD would have been largely wasted, career-advancement speaking.

For a software developer with a regular STEM MSc, there is more of an upper, less of a lower bound, but I'm not planning on testing out those upper boundaries (like, can you rise to C-level of a large corporation? Sure can, but a PhD makes it much easier where I'm from).

In Physics it's not unusual to start a PhD in a sub-discipline that you've got little experience in (I realize the author works more on the information theory side of things). When I started my PhD in experimental quantum computing I had experience with superconductivity and low-temperature physics but none with qubit design or high-frequency RF system design. It's the point of a PhD to learn about these things and g…

Yeah, but at least your PI should know about your field. This is a really weird article and weird PhD experience.

The author is probably leaving out a lot of context. Seems to me they joined a program without really thinking about who they would work with, and then when they finally thought to look they were shocked to discover there was no one they’d like to work with.

Schools offer this kind of acceptance path for students who aren’t very strongly tied to a particular idea. The author, despite having no experience or knowledge in QC was very tied to the idea, which how would the faculty know that before admitting them? Usually when you are so devoted to a research idea you’ve worked on it to some degree before deciding to devote 10% of your life toward pursuing it. I’ve never seen a student quit in 6 months because they couldn’t make progress on an idea they had only just started to consider.
