I know this isn't /adv/ but I'd like to hear from other anons in this board, I'm close to graduating and having doubts about the following path. Over an year ago I decided not to do a PhD because of experiences I had on my first research project: low grants with huge gaps of time where I wouldn't even get paid (agencies/advisors being late), stress and dedication only for something completely out of the blue to shit over my project (again, agencies), and, among many other reasons, hearing my graduated colleagues' experiences.

Everyone doing a PhD said they either regretted their decision or were already privileged enough to treat it as a passion project. Huge stress, essentially being overworked, no benefits or retirement funding, Academia idiosyncrasies. The worst of all was their future perspectives: the best jobs in our country are federal positions where you pretty much can't be fired while also having some decent to great salary, and plenty of these require a PhD. Problem is, we barely get these public tenders, so every 5 years the pile of PhDs and post-docs applies and only the chronically academic 35-40+ years old contestants have a chance because they decided to spend 2 decades farming titles for such an opportunity. I can't even imagine stressing myself doing these projects for ten years, only for a CHANCE at getting a good job.

Meanwhile, the industry feels tempting given the immediate salary is already higher than any grant and I hear less stories of industry folk getting fucked when compared to PhDs. I'm well aware what I make won't be "mine" (not that I care for titles or authorship), and I've also heard that it can be difficult to return to studies once I'm already in (funnily, I've heard the opposite as well). I'm still measuring the possibilities but man, what tires me the most is the feeling that we're always closer to failing than having success, because the good opportunities are scant and you have to plan ten steps ahead, constantly.

I didn't even finish the highest level of high school math, yet managed to apply thinking ability to investment research well enough to multiply an investment of almost $1000 by 30, as well as find an asset that multiplied by 1000 eventually.
Wasn't simply handed that money, though, I wouldn't call 13-hour days of moving boxes at Amazon the hardest thing to do either. My brain cells only finally thought about investing after I fell ill, lost the job and was looking for work.
So to you who managed to do what you've done, if you have the spare money I'm sure you can do just as well if not better... with respect to the fact that not every year has the same opportunities. However, I couldn't even work when BTC first appeared, nor was I into investing when ETH came to be. Didn't stop me from finding opportunities.
/biz/ is a starting point, but one thing people often told me is make sure YOU understand why a project does or does not have potential, so you don't buy just due to hype, nor sell out of sheer panic over a price dip.

>>16864786
I think long-term this makes the most sense, after all the higher positions do indeed require a degree. At the moment I would rather at least get some part-time job or really anything so that I don't have to depend on the PhD grant for the money, since it's genuinely bad. I don't see myself stagnating in either areas because I'm not too fond of the corporativist environment anyways, but I understand why it happens. Sometimes it feels like people realize how bad a PhD could be and decide it's better not to bother, but on the other hand I noticed most people who do a PhD often do so without much planning or higher reasoning. It's more of a "well I'm already here" inertia mentality, which is essentially throwing it up to luck. I'm not the luckiest so I've got some issues in my team, asides from not having a perfect project in mind where I could at least be satisfied with getting better at it. The time off-Academy will be useful for delineating the project, and also planning on who to work with; also, not relying on the grant bs will be an already excellent start.

I do actually have to study investment, thankfully I'm stingy enough to always think ten times before any big purchase so I'll have more resistance to the whole "upgrading your life standard until you actually risk losing it"

The best position to be in is working for an employer who would be willing to fund your PhD part-time while working for them full-time. If you do a PhD I agree with you that those 4-7 years of opportunity loss of not working and having a normal salary is a huge factor in not pursuing a PhD. Salaries for PhD is also variable, some not even much higher than an entry level Bachelors grad. People regret doing a PhD because they realized that those 7 years they spent in school could have been spent working for a company and working up the ladder.
>>
>>16864786
>Not to mention that a PhD can just walk into and grab any BSc or MSc position he wants.
All things equal. The opportunity cost of your PhD is the time you won't get work experience. Compare someone with a PhD and someone with a BSc/MSc + 5 years experience and the latter wins. Most employers don't know what to do with a PhD holder and there are too many PhD holders out there.

Couldn’t be farther from the truth. HR roasties get the ick because they see someone who’s more ambitious and productive than the goycattle they were assigned to hire. It’s like saying bachelors in mathematics have an easier time applying to construction work jobs.

>In that sense, the chart may indeed reflect the end of "evolution",
>whatever evolution can be said to be occurring is non-Darwinian
No and NO. Evolution among livestock is continuing by modern definition..which is just Darwinian evolution + genetics as the hereditary mechanism
Moreover, [your completely misunderstood idea of] "Darwinian" evolution does not require that selection be natural. Darwin talked about artificial selection and said its the same idea he was developing with a different type of selection. Thus livestock breeding/husbandry is Darwinian evolution via artificial selection.

Gemini 3 Deep Think reached 45% on ARC AGI 2 (not to be confused with ARC AGI 1, which is basically fully solved) Humans (mostly STEM students) could only score 60%, on average. So while AI is still behind on accuracy, and it costs more, the writing is on the wall.

GPU number crunching is getting cheaper by approximately a factor of 2 per year these days. And LLM algorithms improve by a factor of 4 per year (see the blog article by the CEO of Anthropic, who wrote about this after DeepSeek came out). This means that AI (measured in intelligence per dollar) is improving by a factor of 8 every year.

Isnt that routinely done when making paper? You dissolve the lignin and get loose cellulose fibers.

Fun fact, lignin is a thermoplastic and wood can be seen as a composite material of cellulose fibers in plastic, similar to glass or carbon fibers. Heated wood (in absence of oxygen) can be bent in shape and welded to other blocks of wood, the lignin just has to stick.

Why are "theorists" in physics useless pieces of shit? They are like completely happy with and proud of being spectators who smugly sit back and observe to give crappy unsolicited opinions. They don't just do that on everything, they also go and try to claim all the fame and credit for everything. These motherfuckers do nothing. If you aren't working with your hands, and instead you're clicking around on Mathematica with some illusions of grandeur, please kill yourself. Obviously you aren't even good enough at math to be better than the Mathematica developers. So just stop. Just quit. Go apply for your Goldman Sachs dream job and leave physics to people who can actually do things.

curious how you suddenly set time boundaries. I’m a HEP guy and you’re absolutely correct that that subfield has gone to shit. But stuff like plasma and solid state are well and alive. I just can’t tell you about the current state of these subfields because they’re outside my specialization.
>>
>>16865890
I have to set time boundaries because clearly theorists were significant in the '20s and '30s. There was also Feynman in the '60s, as well as developers of QCD such as Gell-Mann. Meanwhile, I'm sure you'll agree that after the '90s it's rather obvious HEP theory is shit. Something happened in the two decades of the gray area in the '70s and '80s. Which is precisely when people like Ed Witten showed up.

The next question to ask is, of all the theoretical physicists that exist, how many of them are in HEP?

Yes, if you restrict yourself to HEP as I said. Ironically it’s the problem with experiment, not theory. People hoped the LHC would find supersymmetry, which would open up a whole new avenue for research. It didn’t. People hoped dark matter experiments would detect new particles. They didn’t. The only realistic avenue for tangible HEP theory research today is neutrino oscillation and guess what. Experiments like DUNE and HyperK are set back by bureaucracy and trying to jerk off enough dicks in government offices to get funding. So theorists have nothing else to do but stick fingers up their asses and publish papers on bullshit like stringy dark matter U(1) Higgs portal axions in 69 dimensional N=8 susy AdS with boundary defects. It’s an appalling state of affairs.

Other areas of physics research aren’t nearly as bad. AMO doesn’t need giant collaborations that are 99% engineers and bureaucrats. Solid state comes in second. Plasma is hard enough that theory research is well and alive with the added benefit of milking DoE retards for grants by mentioning muh fusion.
