Good for him. Because of this: "My supervisors have a rather superficial understanding of Quantum Computing, and I feel like their idea to start a project in that domain was to a not inconsiderable extent motivated by the prospect of granted research funds , not primarily by their desire to achieve a deeper understanding of quantum stuff." It's always about grant money. Especially with anything that starts with Quant…

At least in most countries in Europe, where a PhD is expected to be a paid job, and unless you are from a really rich institution, you need grant money to take PhD students. There is no other way to do it, except for taking unpaid students, which is typically not considered an ethical thing to do.

And yes, sadly, being successful in asking for funding means pitching the hot topics du jour, which typically don't coincide with the most important or interesting things to do from a scientific point of view. Although asking for grants in quantum computer having zero experience in it does sound a bit too much.

We really need funding to go to people, not projects. Having to pitch specific projects when asking for funding does more harm than good IMO.

I'm someone who finished a PhD, here's my perspective. You don't believe your supervisor or your research group and so you quit, great. It's great that you have the critical thinking abilities and confidence in yourself to make such a decision. However, I think it's extremely unprofessional to write a blog post saying that your supervisor is superficial or your research group is performative art. I don't say this bec…

In general, I tend to be of the school that, while I won't say you should never blow up bridges with great force, the default should almost always be that whatever satisfaction is gained by publishing a cathartic blog post or twitter thread is probably better written in a diary somewhere without pushing a publish button.

I find that many of the PhD students who struggle are not prepared for the mostly self-driven nature of the pursuit, and have not had enough work experience to know how to choose a supervisor.

The statistics support this: a majority of the PhD dropouts are students straight from undergrad who performed well academically, but have never had work experience.

Finishing a PhD is as much about selecting a good PI as it is love of the science. Anecdotally I've seen many great students struggle because of lack of support from their PI, and many "worse" students do extremely well because they chose a terrific PI who builds a support system around their students so they almost cannot fail.

I quit my PhD with a masters after I heard one really good saying that went against my ADD: PhDs learn a lot about almost nothing. Said differently, 20 years ago, if you got a PhD in chemistry it was typically very specialized (synthetic, analytical, etc) and that’s all you could really do in the field. I business I’ve moved pretty easily between functions and it’s just what I needed personally. I know some people love making new discoveries and becoming the preeminent expert in something, but I think some folks need to be able to jump around with their financial viability intact.

> 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.

Pray tell, where is this Elysium?

I have never heard of a PhD student in computing struggling to find a job.

> extremely unprofessional I disagree. It is extremely unprofessional to act like doing research while pocketing mostly public funds like that. I am 100% behind the author. They have apparently tried to resolve the issue internally and this serves as good warning for people considering science career in today's world.

>I disagree. It is extremely unprofessional to act like doing research while pocketing mostly public funds like that.

This can be true while it's also true that making a vague, unsubstantiated assertion about how your love for the field is just too deep and pure for academia is still unprofessional.

Of the people who claim they dropped out of school because they were just too smart or creative to go through the motions, the vast majority are probably very wrong. If you want people to take you seriously, make a better argument.

I interact very heavily with academics (though am thankfully no longer one myself) and one thing I can't stand is that all of them will complain endlessly about the horribly abusive and broken system that academia has become, then without hesitation turn around and flog the next person in line when it's their turn to continue the process from the abusing side. As someone who once held the title of assistant professor…

> Academics who defend a broken system are a major factor in why that system continues to decline.

Much like military & law enforcement personnel who wear their medals defending a broken system.

The OP should count themselves lucky they have seen that having a few letters after their name on a piece of paper or business card doesnt cut it with many.

Estate agents (realtors) have devalued the letters after name's obedience to "authority".

I haven't finished the whole article, but I can resonate with this specific statement:

> "However, just a couple of months into my project, I figured out, I wouldn’t find anyone to discuss my research with..."

While studying physics and math, many, and I mean *many* of my friends had a difficult time trying to understand both, sometimes they would get bored and just try to get the "just right" grade to pass. I had that one friend that you like to discuss things and exchange ideas and concepts from this world, but this friend would halt his course and move on with other things and/or job.

After some time, I would get bored because none of my fellows had the patience to understand or try to grasp the basics of what makes, at least for me, these fields so interesting, like "bootstrap concepts" (Newton's laws, Thermodynamics, Trigonometry, etc...).

I don't blame them. The basic education in my country (Brazil) is somewhat crippled, not all of it mind you, but in my experience, it was depressing.

And of course, no one is obliged to have fun with this, I'm not complaining about this, I'm sad because there's almost no one I can talk to about this, and not that "I was better" than them, by no means, it's just that had an acute interest in these topics; this is one of the reasons I quit my degree in Computer Science, half a year through.

Nowadays I look for someone to interact with, about something new that I learned or that now I understand better. Right now, I'm looking for a friend that wants to study chemistry, physics or mathematics for fun, but with a deep interest.

FWIW, I’m surrounded by PhDs who love research, loved their time doing PhDs, and some of whom loved working at Microsoft Research. I work in computer graphics. One good thing about a PhD is you get several years to explore a topic of interest to you in great depth. (As long has you have a decently good advisor.) Another good thing about a research PhD is that in addition to getting experience publishing papers, you g…

another good thing about a PhD is that people who have advanced degrees earn on average 50% more than (1.5x) people without advanced degrees This is bad statistics 101. The confounding variable in a lot of these cases is wealth (or social class). Someone who grew up upper class and got their PhD is of course going to earn more than someone who grew up in a trailer park never graduated high school. The reality is that…

Oh this has been well studied. There’s a whole swath of papers teasing out the confounding variables, and wealth is not the only one. These papers estimate the correction factor one would need to assign a portion of causation to the degree, and a portion of causation to the inherited wealth, and basically nobody is claiming that wealth is the complete reason, and nearly all papers assign a healthy portion to the degree after controlling for wealth, for two reasons: one, because unsurprisingly 5 years spent studying actually results in learning a few things and gaining some skills that are useful to industry, and two, because industry relies on credentials, and people without PhDs cannot get research jobs, regardless of how good they are.

There’s no doubt in my mind that things are biased for the wealthy, none whatsoever. But consider patents - they have no degree requirement, and the number of patents granted to people with a bachelor’s degree or less is in the low single digit percent, it’s a landslide for people with formal research experience.

> The reality is that for a lot of people getting advanced degrees leads to nothing

What does “a lot” mean? Do you have a source for this claim that passes statistics 101?

For what it's worth, I burned out sometime in the late 90s just after video cards came out around 1997, because I could see how they would drive video game design towards a narrow branch of DSP/rasterization and building derivative games with cookie cutter libraries. At the time, I was more interested in getting away from all of that and exploring stuff like ray tracing and artificial life. My interest in video games never fully returned in the same way. And if I'm being truthful, I've been burned out ever since, approaching 25 years now.

But after two lost decades, I've noticed a shift lately. I think that people are getting fed up with centralized control of the supply chain and are maybe looking towards things like FPGAs as a way to get to a level above the current imperative programming paradigm, rather than working at the level below it in the glorified DMA transfer and shader paradigm we have now (vertex buffers).

For something as esoteric as quantum computing, I think it would help the world a great deal if someone would go back to first principles and explain it how it is. Not with complex notation, but with counting principles from probability and statistics. I had a great teacher in college who taught it just exactly that way, by imagining small groups of apples and bananas and how we could count them and detect larger patterns to get to stuff like Bayes' theorem.

So for example, we can imagine cubits as coin flips that we haven't looked at yet. If there are relationships between multiple unseen coins, then we can map out that potential solution space like a big tree. Then look at the tree with random sampling of the superposition to infer where the answer probably lies. Which is a lot faster than iterating through all all of the permutations with a computer. But I suspect that convergence will end up taking roughly the same amount of time as brute force, due to noise or some fundamental aspect of the universe we don't understand yet. But I'm probably wrong about that, because I haven't gotten clarity on how any of this stuff actually works, because nobody bothers to write it this way from first principles.

Even if the author isn't going to be doing quantum mechanics in academia, it would help the world a great deal to share what they've learned so far!
