> but after faltering a few decades, it's good to see them publicly redouble their efforts into science and technology If the faltering you're referring to is deflation and economic stagnation over the past three decades, the biggest issue now is population decline ( due also in part to the decades of deflation, and 1.5 generations developing a habit / culture of saving ). Science and Technology is good, and maybe both issues should be addressed, but I'm curious whether a push for STEM is a distraction from these potentially even harder problem

They may no have reached population equilibrium yet. Does Japan have to exist at 115MM people? Maybe it's viable at 50MM. Same for everyone else. Does the US have to have 330MM, or can we be okay with 250MM, or China at 750MM, etc. Declining pops diminish the need for expansionism and internal unrest. Less fighting over limited resources.

  Lower population is good as there are more resources to go around, however there start to be issues as the older generations start retiring and/or are unable to work and have to rely on the smaller younger generations to support them.

  The issue with Japan is not specifically the decline nor absolute level of overall population. It's rather the demographic makeup which is shifting older. The next few decades will be increasingly difficult for them as their economy will need to support a larger level of retirees. https://www.populationpyramid.net/japan/2019/ https://www.populationpyramid.net/japan/2019/ China has a similar issue coming down the line. https://www.populationpyramid.net/china/2019/ https://www.populationpyramid.net/china/2019/ For reference, the U.S. population pyramid looks a bit "healthier" (more balanced), though the retirement of the boomer generation will still pose a challenge. https://www.populationpyramid.net/united-states-of-america/2019/ https://www.populationpyramid.net/united-states-of-america/2...

    That's the usual specter; however, before modern times, populations grew and shrank for many reasons. Once people were out of the weeds from childhood disease, people lived reasonably long lives. One big difference now is people expect to "retire". That's a modern construct. Sure, people used to add less and less to society as they aged and ultimately would need some subsidy, but much less than today.
    - bserge 5y ago
      They expect it because it's been the norm for a couple of generations. And we're paying a lot for it (in Europe, at least). But yeah, it looks like we'll go back to no retirement soon enough, the current systems are not sustainable. Lots of people will be pissed off.

    > The next few decades will be increasingly difficult for them as their economy will need to support a larger level of retirees. How do you come up with this stupid idea? Japan has deflation and slow growth because of demographics, meaning the economic problem is the exact opposite. Old people spend very little money, meaning they need very little support to take care of them. The economy is dying because those old people don't spend their money, resulting in surplus workers that can't find well paying jobs who then subsequently drop out of the labor market. If old people somehow spent all their life savings on medical bills to stay alive for one more year then a lot of young people would end up getting that money. Those young people have a whole life time of earning money ahead of them. It's only when you deny them the ability to earn that money that they suffer. Full employment will just create more demand for increases in productivity which then results in greater increases in productivity than one would expect if there wasn't urgency.

  We’ll be better off as a species if we find a natural stable state, but that doesn’t mean that getting there will be a good experience for everyone. Shrinking populations in particular puts a lot of strain on workers to support a larger elderly population. The more rapid the decline, the worse the strain is.
  - tbihl 5y ago
    We would be much better off as a species if we were able to handle the transition to a stable state. On the other hand, population growth is what allows us the enormous specialization that lets us achieve unbelievable technological feats while also wasting time during work on HN.
    - mc32 5y ago
      There are enormous amounts of people who don't add to innovation. Very few people are needed for innovation. Most people even on HN are doing routine things. Not discovery or in support of discovery. Most people's minds are not being taxed -and that's okay. That's to say, having millions of idle minds to produce one very productive mind isn't a requirement. I think this initiative could be part of this solution where we need fewer raw numbers but more productive percentages.
      - tbihl 5y ago
        Two things: first, without having a recipe for very productive people, our best option is fostering fertile environments for development and then seeing who comes out, and that's very much a numbers game of getting as many entrants as possible. Second, the trail of supporting cast for any technological development is enormous, and we're making a huge mistake when we forget that. Not just the people who clean the streets and the buildings, but the people who build them, design them, maintain them, create the organizational and financial structures that keep them operating, and so on. And a few of those roles aren't very low end, just to keep the static pieces of the built environment from falling apart, just so you can get to the point where there's somewhere to live for the people fixing bugs and writing documentation for the the libraries you want to use multiple times a day, quite likely for free, without asking anyone for them or even giving a second thought. And it's not like those were written for you: there are dozens of implementations in as many languages, just waiting to be picked up. Things get massively more difficult for you if those tools are being produced for you specifically (that's what military procurement projects tend to have.) That obviously does nowhere near justice to even a simple software project. Now take that x1000 for any hardware project, where the raw materials, processing, and logistics circle the globe several times on their way to you.
- Taylor_OD 5y ago
  My understanding is that the issue with declining population is that typically that also means an aging population. Younger people are not having children which causes a whole slew of issues.
  - tbihl 5y ago
    What you've described is the best-cast scenario of an aging population. Far worse is the modern reality in most places, which is systems that take growth and a certain demographic shape as base assumptions, and then make promises to people decades in advance based on those promises. That's what we do in the United States (and probably most places, but I won't speculate.)
- JohnWhigham 5y ago
  I think this switch from supporting an always-growing economy to one that one whose population numbers are in relative stasis will be the biggest challenge of this century. It's something we've never encountered as a global civilization. And I think it could break said civilization.
  - mc32 5y ago
    The "always growing" part, I think has a lot to do with the stock markets and public companies. Private companies can go up and down, expand and contract (it's not painless of course). But a lot of this is due to expectations. Society can adjust if it's allowed. Before the 1900s old people didn't retire (unless they were wealthy and never actually did hard work). Maybe we need to rid ourselves of the idea of living idly with golfcourses and driving an RV all over the country and instead to add to the household, if in diminishing amounts as one ages.
  - breckenedge 5y ago
    It’ll be rough no doubt, but the Black Death didn’t break civilization, and it was a much more drastic population reduction. I do wonder how we will accomplish really big projects, such as properly decommissioning nuclear power facilities, with a reduced population. All of the models for licensing and re-licensing reactors assume population growth, and doing it wrong or neglecting it could lead to some really fucked up situations.
  - toyg 5y ago
    > It's something we've never encountered as a global civilization I'm not sure what that means. There have been periods of population stagnation in continent-size swaths of land before. Culturally speaking, stagnation has effectively been "official policy" in Europe for centuries, before the XIX/XX century changes. It ended simply because technological advance by growing societies made it culturally unsustainable to pursue ideals of eternal stagnation. If you don't grow, somebody else will and eventually they will show up at your door. This is also the case of Japan, btw. They were effectively forced to grow and progress by foreigners demonstrating military power and tech that they could not match. If they stagnate too much, they are at serious risk of somebody else (China) doing it to them again. If you think a global policy of stagnation would not have such drawbacks, you're effectively stating that no interplanetary species will ever show up at our door with big guns, ever. That's kind of a big gamble.
- tbihl 5y ago
  >Declining pops diminish the need for expansionism and internal unrest. Less fighting over limited resources. This is probably true, but the problem is that its logical conclusion is the literal death of everyone. Stop anywhere short of that, and people will return to the point where they're no longer too preoccupied with avoiding imminent death to compete for resources. At that point, the less fighting is unlikely to be less per capita, and the only good thing to say will be that technology will have regressed so far that we won't be able to fight and kill very efficiently.
- cactus2093 5y ago
  Sure the US could probably exist with 250MM people, in the sense that there are certainly countries which are smaller than that which are doing well. But the path to get there would be shockingly painful and result in a huge decrease to the average quality of life. The path to get to 500MM or 1B people on the other hand would bring about a huge increase to the average quality of life. You have it backwards thinking that life is better if the population shrinks. This is getting into a whole other can of worms but I firmly believe the most moral path for the US to aim for is the latter.
  - mc32 5y ago
    Could we? Maybe. I don't think we want to. Not the way we consume our resources. We already have water issues in much of the country when there is a drought. We do not need that many people. The planet does not need it. We need to learn to live with less and without never ending growth. Just as we target the 1990s or some other period for C02 production, we should do the same for population stabilization. A couple of droughts here and there (as we used to suffer from in the past) and we'll have massive hunger and famine problems. We need slack in the system for safety. We cannot operate at the limits and not expect catastrophes.
    - astrange 5y ago
      Peak water use in the US was decades ago and isn't related to population growth, nor does economic growth require increased resource use. It requires efficiency. Degrowth is just killing people, in which case the people proposing it rarely want to go first.

        Population decline is not killing people. Japan and S Korea aren't killing anyone.

        Economic stagnation, caused by population decline in the absence of robust productivity growth, leads to social problems and the so-called "deaths of despair" in the US. Haven't seen statistics on elsewhere.
