    That is exactly how I described it to my therapist when I started really getting my mental shit together a few years ago… past 40.

    There has been another recent meme that says something along the lines of “do you know they let you raw dog ADHD your whole life as long as you get good grades?” and that one hits even harder. I’ve described my childhood academic performance to a few of my medical professionals as “I was the kid who was threatened with getting kicked out of the gifted program because I didn’t do my homework.” And honestly I don’t think I remembered the assignments existed. I think that was the year I started using big fat daily planners.

    And along those lines, while some of us are venting about difficulty getting treated: In past decades I’ve hauled my ass onto psychologist offices for an ADHD diagnosis and treatment. Well, I’ve always done well on cognitive tests. And you’d better believe that my Rejection Sensitive Dysphoria makes me hyper focus on those tests like a mother fucker. So being told you’re essentially too smart to have ADHD is frustrating as hell when you have failed university classes and gotten fired from grown-ass engineering jobs because of a crippling lack of executive function.

    And I want to be clear none of this is supposed to be humble bragging. I’m just assuming that the audience on Lemmy is dense enough with similar computer nerds that others can probably relate when I describe it plainly. My brain is not one to envy — let’s just say it has lots of Simpson-esque “speed holes” thanks to other more significant medical shit, lol.

    Edit to add: speaking of RSD, the first time I read about the strong link between ADHD and Rejection Sensitive Dysphoria, my entire god damned life made sense. Why yes, my life has also been defined by crippling social anxiety!

    But the silver lining there is that I am able to make things a lot better for my son (8) who is exactly like me, and I can teach my wife about the brutally powerful emotions in situations that just don’t phase other people.

    But can electromagnetism at all emerge if the quantum mechanics dont exist to emerge things like magnetism and some of the behavior of electrons?

    Well yeah, sure. Earlier you said something like “electromagentism is caused by quantum phenomena,” but you can say that about almost every object and behavior in the universe! We don’t have a theory of everything but the standard model and quantum field theory explain a lot.



  • I can totally see this coming.

    The developed world has a population growth problem. Population growth has slowed or reversed in many countries, but the global economy is designed around infinite growth, fed by an infinitely growing pool of workers and customers. Then when they retire they can be taken care of by the infinitely growing population of young people.

    It takes zero imagination to picture this administration forcing “high value human resources” to remain in the country, including putting them on no fly lists. Unfortunately since they are stupid, the brain drain has already started.




  • 10^24 is a lot bigger than 6×10^23

    Well yeah it’s almost double, but I wrote the comment as a mental estimation of the order of magnitude, so it doesn’t change the substance of the discussion.

    I mean at the beginning I arbitrarily picked a number in that 10^40 to 10^44 range and that’s a factor of 1:10,000 rather than 1:2, lol.



  • This was a fun one to look up. https://en.wikipedia.org/wiki/Shannon_number

    It looks like the number of valid chess positions is in the neighborhood of 10^40 to 10^44, and the number of atoms in the Earth is around 10^50. Yeah the latter is bigger, but the former is still absolutely huge.

    Let’s assume we have a magically amazing diamond-based solid state storage system that can represent the state of a chess square by storing it in a single carbon atom. The entire board is stored in a lattice of just 64 atoms. To estimate, let’s say the total number of carbon atoms to store everything is 10^42.

    Using Avogadro’s number, we know that 6.022x10^23 atoms of carbon will weigh about 12 grams. For round numbers again, let’s say it’s just 10^24 atoms gives you 10 grams.

    That gives 10^42 / 10^24 = 10^18 quantities of 10 grams. So 10^19 grams or 10^16 kg. That is like the mass of 100 Mount Everests just in the storage medium that can store multiple bits per atom! That SSD would be the size of a small large moon!


  • We as a society did not forget how to build good houses, write good software, design good vehicles, or anything like that.

    We just stopped caring about it because the core purpose for any business is to increase revenue, decrease costs, grow, and absorb market share (exceptions being niche and boutique places that price accordingly). And may of us as individuals think we should run our own finances in a similar way.

    For instance, let’s say I can build 100 shitty crooked houses with the cheapest and non-background-checked workers, with the same time and money invested that it takes you to build 50 beautifully crafted and solid homes with your team of experienced carpenters. I can sell my shitty homes for 20% less than you since the home buyers are also mostly shopping on price and stats, then I am going to win and once you’re out of business I will be building 150 shitty crooked houses at a time.
