Complete? I wouldn't say so - as others have noted, there's a few issues that the author of that blog post has with some small assertions made by Matthew Walker.

Whether that throws everything in the book into question is an interesting question, but if the whole book was 'complete bullshit' then I'd expect a more comprehensive debunking than that blog post.

As to the links you've cited there -- 1 and 3 are the same link (well, HN comments in (1) point to the actual story at (3).

The second link seems to agree with -- and be full of exactly the same myth debunking & recommendations that -- Matthew Walker makes. As it happens I'm about 80% the way through the book now.

At least sometime in your 40s, people stop saying "Oh, you'll change your mind. You'll want kids."
Thank you for this AMA, it was eye opening and made me think a lot about the organizational/tech debt barriers to creating AGI (or creating an organization that can create AGI).

I'm a ML researcher working on Deep Learning for robotics. I'm skeptical of the symbolic approach by which 1) ontologists manually enter symbolic assertions and 2) the system deduces further things from its existing ontology. My skepticism comes from a position of Slavic pessimism: we don't actually know how to formally define any object, much less ontological relationships between objects. If we let a machine use our garbage ontologies as axioms with which to prove further ontological relationships, the resulting ontology may be completely disjoint from the reality we live in. There must be a forcing function with which reality tells the system that its ontology is incorrect, and a mechanism for unwinding wrong ontologies.

I'm reminded of a quote from the Alien, Covenant movie.

Walter : When one note is off, it eventually destroys the whole symphony, David.
If you are trying to work a full time job and then do side work on top of that, it won't happen with kids. Your full time job is even more important when you have kids because that's all the time you are going to devote to your career. You have to be in a place that's interesting and where learning happens at the office.

As for whether you have no life, well, I think this is life. It's far more fulfilling than when I spent my time outside of the office futzing around on somewhat productive hobbies that were ultimately not life changing.

The hardest part has been staying close with friends. I'm lucky there in that a bunch of my friends had kids at the same time so we all made the transition at once. Suddenly instead of going out to bars we all want to hang out on a Saturday afternoon with our kids. Without that I genuinely don't know how we'd keep our adult social life going.
1000% the same. I often get motivated to mess around with or learn something for the sake of it, but have a very hard time choosing something to get motivated to mess around with or learn about.

Give me someone who needs me to build something I don't already know how to build, though, and I will figure that shit out.

I've been lucky that this has worked out well for me so far, but it means I need to always try to get on projects with unfamiliar things or take new jobs involving unfamiliar things, or I'll have a really hard time expanding my skillset.

Oh, and school sucked.
Moreover he's using the large amount of wreckage to argue that the Darwinian process of selecting "category killers" isn't working, which is completely backwards.

If "category killer" is a winner-take-all competition, then there are going to be a vast number of losers, and we do see a vast number of unmaintained projects. It's just that no one is bothering to remove them from view when they're defeated.
Counter-point: if a programmer is successful in delivering business value, the programmer might have an inflated view of their programming abilities. I know I certainly have been affected by this. Being able to get things done does not necessarily make a person a great and talented programmer, but it may make them accomplished.

My projects have grossed a lot of revenue, but several of these projects would be challenging for me and push my the limits of my skills.

What I am saying is that there is room for more nuanced language to describe all these matters in a way that is detached and clinical.

Exactly.

Also, hourly quotes for even the most basic things around the house are a poor idea. Someone recently told me she had to move to fixed bids for everything with her handyman because he would just move really slow when it was hourly.
No - I wouldn't have been able to do the job.
At least in Germany, the electric infrastructure is mostly up to the task, switching to all electric cars would take only minor improvements, mostly adding more local transformers as the electricity/household is going to raise most of all. Overall, it would mean a mere 20% of more electricity consumed. Also, as charging is a nicely controllable load, electric cars could stabilitze the grid.

Modern electric cars can be recharged in well under an hour, so "hours" is off - unless you charge over night, where it doesn't matter.

For hydrogen on the other side, you would need a complete new infrastructure. Hydrogen fuel stations have nothing in common with conventional gas stations and are really expensive ($1 million/pump). Also, there are restrictions in setting them up in residential areas and while you might be able to refuel a hydrogen car in not much more than 5 minutes, there is a dead time in which the pump cannot serve the next car until the internal pressure has been restored (like 15 minutes).
It's not nostalgia, I didn't grow up with Japanese culture. And it's not that I can't understand it - I can. I just like the music. Japan has the second largest music industry in the world after the US. They produce a huge, diverse group of interesting music which stands fine on its own merits.
It's much easier to add some carbon into your hydrogen than it is to deal with all the problems that hydrogen bring.
Maybe not directly. However, the article does cite the Gender Equality Paradox:

"Contrary to what one might expect, for all of these personality effects the sex differences tend to be larger-- not smaller-- in more individualistic, gender-egalitarian countries. "

This finding, which apparently surprised and puzzled everyone, is very difficult to square with the idea that it is the societies/cultures that are creating these effects, because then you would expect the correlation to be the other way around. So not a magnitude difference, but a sign difference. Again, that observation, which has been replicated repeatedly with ever larger sample sizes and larger effect sizes, just isn't compatible with a cultural source.
The concept does need some qualification. “Small software” can probably become “done.” Grep, as an example, is done. Frameworks, libraries, and applications all have a steering wheel requirement of support.

I’d suggest that a fair amount of github open source is resume padding, or at least an attempt at it rather than “scratching a developer’s itch” which the original ESR paper mentioned as a reason.
It's not hard to build a ride sharing app.

It is, however, hard to get drivers and customers FOR your ride sharing app.
Yes, that was my point. I have never sold a car that had material resale value. (And, in fact, just donated one--which was about 20 years old.)

I do think that new computer tech-type features may be shifting the equation to make older vehicles less attractive more quickly. Although I'd argue those are probably more important for the driver than the passenger--modulo some safety features.
It seems fairly pointless and meaningless to argue whether someone "is a genius" or not.

Check out this recent short video of Magnus being shown and recognizing positions from Vishy Anand games.

https://www.youtube.com/watch?v=acVvkz4MsKc

Common might be recognizing the opponent and next move (I, patzer, got half right, also that the move against Lautier was h6!), but Magnus also remembers the year, tournament, most of the game etc. He has a remarkable memory, and studies a lot of games, past and present – because he loves doing it.

Bobby Fischer was similar, from what I hear. I've read quite a few stories of people from around the world meeting him and he'd say "I liked your game against X 10 years ago but you should have played move Y" and they were amazed he'd even heard of them, let alone studied their obscure games. (This was pre-internet and pre-computer-analysis)
Conspiracy hypotheses.

I'm still getting a bit done, nothing like I used to, but getting out is all the sweeter when it happens. We have a toddler. She came to Scotland with us in the van this summer and my friends dragged me up two sea stacks... Lovely trip :-) The little one likes to hang in the the van side door like Alex Honnold. Last year my wife kindly spared me 2 weeks to go new routing abroad though honestly it felt like a long time to be away. (I returned the favour while she went on a yoga retreat, not for nearly as long though).

I do plot a return to fitness one day! Although I primarily used to climb outdoors (and now have a crag within walking distance of the house) I do miss living near an indoor climbing wall for the convenience of climbing any time of day, any weather, partner or no. It's all about the convenience when you have to fit it around job and parenting. Mountain biking as one sibling comment said is far easier logistically (and right now I'd rather teach the little one to mountain bike - lower consequence I think - climbing can wait a bit). Caving as well as it's a proper adventure I can do on dark wet evenings near home.

One climbing couple I know I saw in the wall for years taking turns child minding / bouldering. Anything can be done with enough dedication, it's just harder. Hey, Dave McLeod still pushes e11/12(?) with parenting responsibilities so honestly operating many rungs below that I have little excuse.

Paul's line in the op about not actually using all those freedoms before I had a child really resonates with me though. I went to a lot of amazing places and did amazing things but only for like 10 percent of my leisure time in the average year (maybe 70 percent in a keen one). The years when I was climbing my best came to an end long before we had a child purely because I got bored of maintaining the necessary fitness.

One thing I will emphasize is having a child ties you to a location more than ever before in terms of jobs, friends, support networks and before long, schools. I'd love to live somewhere more mountainous than the UK one day but now it's not the right time for the family. Will it ever be the right time before I'm too old to climb the routes I want? Who knows. If I relived the last 20 years I'd have done more of it in different places and possibly picked a different place to raise a family. But things are rarely that simple of course.

Would I change our child for anything though? No way :-)
Sure. That's why I wish I could do LUKS authentication via TPM, which can do hardware rate-limiting. Is this kind of setup possible these days?
I don't understand why it's a moral imperative that people not take advantage of the VC funding subsidy? The VCs are wealthy interests looking to find a 10-20-100x exit at the end of this. I don't care if the Saudi Royal family places an enormous bet on automation over the next 10 years. Why is it for the best that all the people who use Uber not have that? I just don't understanding cheering that one of the few subsidies that is tricking down is being phased out, and I disagree with the suggestion that any of this is driving toward the end of paying drivers more.
It seems like a silly metric. Almost all code gets abandoned, and at an alarming rate. Unless you happened to build a popular database or an operating system component, it’s likely that your code is gone in 10 years. And if not, your code is likely the future bane of some developer who despises maintaining it since it is such a bear to update to their unforeseeable requirements.
Ultimately , I guess all you have to consider about having children is how much you need/want "to love" and "be loved in return".

Once you have that answer, you can deal with the rest (emotional/financial/relationship/time stability and security [sorted alphabetically for no reason]).

Also, props to PG for writing one of the more coherent articles on having children.
Proper glovemaking actually requires a surprising amount of skill. Even crappy gloves do.
I don't think most people literally believe every man is stronger than every woman.

I think it's much more common that someone will say "of course there are some women who are stronger than most men" then go back to tending to, for example, hire men over women for a job requiring the ability to lift 60 lbs, without bothering to strength-test female applicants.

Y'all got any of them AIs for turned based strategy games?

Seriously, I'm starting to think turn based strategy games like Civilization, etc, will be the last to get any attention. Why? We need good AIs for these games and they're not yet solved as far as I know. Furthermore, you don't have to model the human interface by limiting actions per second like with DotA or StarCraft. Yes, we solved Go, but turn based strategy games on PC are more complicated. Seems like a worthy area to research.

Does anyone know of any work on games like these?
Dude, where are the code samples? You lost me by not having them. I want something nice like Svelte.
Base R is fine. I would much rather not include the tidyverse and all of its transitive dependencies.
I'm curious how this study compares to the average research coming from social sciences which seems to be generally accepted as valid.

IIRC 30%+ of F500 CEOs are 6'2" or taller
Sure. That's just how things are when you have kids. You'll get better at management and they'll need less attention overall, but that's it you got your main project running now.

In the other hand, I never had such a fruitful experience. I can teach my kids. I can make them respect my daddy time. And I can let them help with the chores.

It all comes down to honesty. Honesty bro yourself, your partner, and your kids. If a side project is what you want to do. Tell everyone and make a schedule. The thing is, even if kids are the most fragile and beautiful part of a family they are but a part and need to understand that at some point.
"> solar energy and wind power and wind-generated energy, to make hydrogen using electrolysis

And this sounds definitely less efficient than using electricity directly"

Of course not. But since you do not want to drive with a cable on your car you allways have to transform the energy.

And the overall efficiency with fuel cells is much lower, but it has other advantages. Like the potential unlimited storage element water (plus iron for the tank walls), compared to limited avaiable batterie ressources.
Hand it over. It's hashed anyways
I would heartily recommend "Children of Time" (Children of Time #1) by Adrian Tchaikovsky. Another one that stands out over the last couple of years (for me) is "The Book of Strange New Things" by Michael Faber, which has a mix of hard sci-fi with some very thought provoking philosophy/religion.
I have imposter syndrome, and what's worse I'm really shy and have trouble looking people in the eye which makes me seem like a liar. What helps me a lot is the move companies are making towards remote interviews. For some reason with skype I can look people right in the eye, it's probably because they're off-center visually or because I know they're not really here. However, that only helps with the shyness it doesn't really solve the imposter part. And, it's not because I'm not competent, I've successfully shipped every project I've ever been part of.

That's Ben Rich's book, right? I have read it twice, and it's pretty incredible. And the amount of details he's had to leave out (such as creating a hybrid turbojet/ramjet engine nacelle or a top speed of around Mach 4) is also interesting. As an aside, I got to see (and surreptitiously touch!) an A12 in Seattle at the Museum of Flight recently, and it was just incredible.
Database Internals
I understand that. I was lucky having dedicated parents, that were willing to sacrifice their own ambitions, and take risks that would clearly be more beneficial to me, rather than to them.

Others, might not have been so lucky.

For me, caring about my own children's health/well-being/future was bit eye opening, in the sense that I was a lot more egoistic, before becoming a parent.

I also think that recognition improved my spousal relationship.

And that's what I wanted to tell my Dad... but I missed that opportunity...

There is a lot of materials out there about family dynamics that get passed through generations. [1]

It is exceptionally difficult for an individual to recognize negative traits that must be filtered out, if he/she is to have a more normal relationships with their spouse and their children.

Most families have traits, that overtime, should be filtered out. But not forgotten.

Significant portion of my parent's upbringing was dictated that their parents went through (physical torture, captivity, war, loosing loved ones, loosing first families during war, real famine, property taken away, ridicule and persecution at work and otherwise, for their ethnic background and so on ).

My parents, filtered out lot of the family dynamics that was passed on to them due to the above.

But we did not forget what my grand parents went through..

And just like my parents,
I do not excuse my own actions by saying 'well, my parents that that to me...' or anything like that.

It is a conscious act, not 'natural' (at least not for me), and I work on it with my spouse, recognizing that there is nothing wrong in improving what we learnt in our upbringing.

You're right. I had a look at the methods sections of three of the four
studies cited in the article. It seems how they collect data is they have
people fill in questionnaires, then calculate personality scores based on
those questionnaires.

For example, in the Mac Giolla and Kajonius study [1] the data came from an
online questionnaire.

I'm finding it very hard to criticise the methodology of this sort of study
without [edited out] being extremely rude and dismissive to a whole
field of research. But, I really don't understand how all this is supposed to
make sense. I look at the plot in the middle of the Scientific American
article that is marked "Agreeableness" on the x-axis (with a score from 1 to
5). I look at the papers cited. There's plenty of maths there, but what is
anything calculating? What is "agreeableness" and why is it measured on a
scale of 1 to 5? It seems to be a term that has a specific meaning in
psychology and sociology, and that ultimately translates to "a score of n in
this standardised questionnaire".

But, if you can just define whatever quantities you like and give them a
commonly used word for a name- then what does anything mean anymore? You can
just define anything you like as anything you like and measure it anyway you
like- and claim anything you want at all.

At the end of the day, is all this measuring anything other than trends in
filling up questionnaires? Can we really draw any other conclusions about the
differences of men and women than that the samples of the studies filled in
their questionnaires in different ways? Is even that a safe conclusion? If you
take statistics on a random process you can always model it- but you'll be
modelling noise. How is this possibility excluded here?

All the statistics are quantifying the answers that respondents gave to
questionnaires and how the researchers rated them - without any attempt to
blind or randomise anything, to protect from participant or researcher bias,
as far as I can tell (I'm searching for the word "blind" in the papers and
finding nothing). In the study I link below, participants found the website by
internet searches and word-of-mouth. The study itself points out that this is
a self-selecting sample, but what have they done to exclude the possibility of
adversarial participation (people purposefully filling in a form in a certain
way to confuse results)?

There is so much that is extremely precarious about the findings of those
studies and yet the Scientific American article jumps directly to d values.
Yes, but d-values on what? What is being measured? What do the numbers stand
for?

This is just heartbreaking to see that such a contentious issue is treated
with such frivolity. If it's not possible to lay to rest such hot button
issues with solid scientific work- then don't do it. It will just make matters
worse.
