Re: Ask HN: Will getting a PhD lead to a more interesting life?

I have a PhD (in mech engineering) and work in industry. My experience was that I basically had to pick up a new physics set and tool set every year as I jumped from algorithm development, to constitutive model development, machine learning, and quantum computing. In all cases they were tackling problems in different areas: new toolset to learn, new math to learn and new physics to learn. I thoroughly enjoy working o…

These are all fair points and worth thinking about for the OP (or others in a similar situation). I got engaged and married while pursuing my PhD, and I found having a wife difficult, it wouldn't work (for me) with kids (although there were a few).

I worked for two and a half years before going back to school but I lived like a student for those years, so I didn't end up with a lifestyle change. I also saw a reason to get the PhD--I wanted (and still do) to be a P.I. on research endeavors.

I got my BS in CS 16 years ago. I always thought I'd go back for a PhD, but every time I started looking, I quickly lost interest. (I don't think I'll ever get one.)

But, here's the important quote:

> After I acquire my PhD, I surmise that I would go to industry.

Go into industry first. Why do I say this? I've been involved in hiring for about 8 years, and I've only seen a very small amount of candidates with PhDs. (They usually come from inexperienced recruiters who don't know how to hire software engineers.) The candidates fresh from a PhD program usually have very little experience in complicated software engineering, and thus will work at the same level as a recent college grad. The only time they are useful is if their field of study directly applies to the work we're doing; but I've never seen a PhD candidate like that.

The thing to realize is this: (Computer Science) != (Software Engineering). Industry mostly does software engineering; it only gets into "computer science" if you're writing a compiler, a database, ect. So, unless you pick a field of study that industry will need when you graduate, you'll end up being as useful as an entry-level CS grad.

BTW: If you find something interesting, you can always leave industry to go back to school. It's critical, however, that you set up your finances to do that. Going back to school will be a huge paycut, so you need to make sure that you don't have a big mortgage, large car payment, ect. (That being said, assume that you'll work for 5-15 years before going for a PhD, so if you buy a nice car now, and pay it off, you'll start your PhD program with a free used car in good condition.)

I've been thinking all morning how to answer this. Rather than give advice, here's some thoughts about what I've seen in the industry. The quick answer is that, yes, a PhD should give you a more interesting life...but you might not want that. I have a PhD in Chemical Physics. I got it about 15 years ago. The need to go deep into computation to solve chemistry problems is what gave me the computer skills that have ser…

This is a very good answer!

I got a PhD almost 20 years ago (in ML). I worked hard and played hard - and had the time of my life. I learned to surf, got a black belt in Aikido, restored a sailboat, climbed 3 times a week, and made friends for life.

Professionally, it set me up to join industry, and put me on a technical fast track. Do I still use any of the research from my PhD - almost never (although I still dabble with NNs and GAs occasionally). Do I still use the overall research and organisational skills, and the critical thinking I learned - every day!

If you are a self-starter and have the right sort of intellectual curiosity, a PhD will be a worthwhile exercise, whatever you do afterwards. And, as the parent points out, the signalling that a PhD gives can be very useful. The fact that you completed a PhD points out that you are both smart, and can get things done.

Number one, unless you love what you study, don't get a PhD. You'll probably never finish.

Number two, if the only reason you want a PhD is for more money, you won't make and it won't help. If you look at the earnings of people with a PhD vs. people without one (but who could have gotten one), the ones who didn't are pretty even because they have four/five years of work experience when their friends are just getting out of their PhD programs.

If you don't like doing reading and research, then you probably won't make it through the PhD. Even worse, the "interesting" work that you get to do in industry with a PhD vs. without is basically more of the same, because all of the stuff that isn't like that is just as open to people with a PhD vs without.

It sounds like the PhD really isn't for you. Get out there and go apply what you've learned thus far.

If you have reason to suspect that the job market will be somewhat recessed in the coming time then getting a PhD might be a reasonable strategy to ride that time out.

I tend to disagree with this. PhD's tend to work in advanced areas of companies. When recessions hit, R&D is one of the first places to take a hit.

I think the idea is that you spend the recession years in a relatively safe albeit badly paid position which can potentially lead to more lucrative opportunities in the post-recession years. This makes some sense except that your skill in predicting recessions is likely horrible and you probably shouldn't be planning your career based on it.

This will sound rude and I’m sorry but there is no way your entire life is ruined because you decided to get a PhD from one of the top 5 most prestigious institutions in the entire world.

I totally believe it. Debt sucks. Being smart (passed a certain point) sucks. Plus, think of the lock-in, losing friends, etc. Basically, he sold his soul, and I don't blame him for thinking he's not going to get it back.

I'm prepared to believe that going deeply into student debt can have this effect. It is a very insidious form of debt that can't be discharged through standard bankruptcy.

My understanding is that it's possible to avoid this through TA or RA positions with tuition waivers, at least at reputable programs. So I think the question of debt should be considered somewhat separately (though not entirely separately, as this insidious form of debt doesn't existing the world of stupid mortgages or credit card irresponsibility, where at least you have the topic to collapse in bankruptcy and, 7+ years later, start anew. Forever debt lives in the hellacious realm of student loans, divorces, and Dickens novels).

I mastered out of my PhD program, largely partly because I got a good job outside with money and fun projects, and partly because I was struggling academically. I do occasionally "wish" (eh, not really) that I had a PhD, but that's because I work in a university (although in a technical track). I accept that research positions aren't open to MS holders in Universities (or in some industry positions), but the degree ceiling definitely extends into non-research positions that would be available to MS (or BS or no degree) holders in non-university tracks. This, however, is my own deal. If I don't like it, I need to leave, so I wouldn't expect anyone to give this complaint much force.

I agree with you on the point that money is overemphasized, but does a PhD really mean you're more likely to add great value to history and humankind?

Yes, that is basically the job description; the point of a PhD is to contribute new knowledge.

I would argue that, while the pursuit of new knowledge is surely admirable, not all of it can be assumed to meet the high bar of being of "great value to history and humankind".

> Industry mostly does software engineering

I would extend this thinking even further...

Most industry jobs aren't even practicing "Software Engineering". Algorithms, data structures, discrete math... that's totally outside of the day to day work for most "Software Engineers"

If you're building an app (web, mobile, desktop) it's largely plugging pieces together nowadays. You're likely using libraries that were built using "Software Engineering", but the end user practice of assembling those pieces into a functional user-friendly application is more akin to a construction worker assembling the 2x4s to build a house.

> I'm afraid I won't be able to find interesting work with just a MSc, and I'm really afraid of getting a boring software engineering gig.

This is probably true. Most jobs you'll get with a BS+Msc are going to be app development. Web, mobile, server... pick your flavor. You'll largely be using tools developed by other people, to build applications.

The really interesting jobs are absolutely held by Phds. But that's not to say that having a Phd guarantees you'll get one of those jobs.

I think if you have the option to get a Phd, hunker down, and do it. The industry is headed for a correction in salaries soon. Way too easy of work is being done for 100k+ salaries. When that correction happens, you're going to be happy that you have a Phd and are doing work in a much more challenging field that warrants the pay.
