To use MathJaX, put your TeX code between [ math ] ... [ /math ] tags for inline equations or [ eqn ] ... [ /eqn ] tags for block equations.

[eqn]\zeta(s) = \sum_{n=1}^{\infty}\frac{1}{n^s} = \frac{1}{\Gamma(s)}\int_0^{\infty} \frac{x^{s - 1}}{e^x - 1} \mathrm dx[/eqn]

I AGREE. Most studies should have some economic benefits or a return on money spent. Why waste it on things that don't make us more productive. With trillions in debt it's mostly an exaggeration but a good example of why these studies don't have any benefit for the public long term.

But but we need to learn and have knowledge. Sure but that can be done in your free time.

Its just wasteful.

We need to spend money on things that can realisticly progress society And add economic benefit

You cannot fix an ADHD brain with anything but dopaminergic drugs the same way you cannot make a car run off wine.
Sure, the car can run a little bit off the ethanol in the wine, but ultimately you cannot perform like you can on petrol.

Your brain is not made for the current farmer society. ADHD is a hunter-gatherer trait.

I went through a similar path.
Wasted years of my youth trying to brute force through it through different means.
Recently, I tried Vyvanse, and it was fantastic.
It really felt like I had escaped a decade-long period of depression. I felt healthy and excited and determined for the first time in years. I even managed to escape being a NEET and landed a decent job.
But now, I've come to realize I am quickly building a tolerance to it.
What once lasted ten to twelve hours now lasts only four, and all of those honeymoon-phase effects of positivity and clarity are practically gone.
What remains of it is like an extra strong, extra crisp cup of coffee.
It's nice coffee, but nice coffee by itself isn't exactly life changing.

Schizophrenia is often correlated with heavier aging, errors in energy metabolism... You should attempt to fix those.

Also a schizophrenia is lot of fabricated, half of symptoms is caused by pill you take for it.

Also there's this thing called GTS-21, which maybe JFK Jr. will push to the market, as it's non-hummiliating, working schiz medication.

Yes, and? Are you trying to imply this means it doesn't matter that humanity will go extinct and we shouldn't prevent it?

I will repeat the question i already asked - would you refuse life saving surgery or cancer treatments? Be honest now.

As i said, critical lack of foresight, though I don't think it's even genuine. Why don't you get a huge loan you will never be able to pay off then? You could improve your present circumstances immensely, and it's not like you should worry about the not being able to pay it off in the future, right?

I care very deeply about the future of humanity, and so did Ted I think until he lost his marbles (or had them stolen by monarch cultists) . The pyramids indicate very clearly that this is not the first time lasers have littered the landscape. The technological progress seems 'braided in' to trans-humanism. I'm stuck on the connotation of this suffix. what are we, humanity, crossing over humanity into?

The philosophers say before enlightenment, chop wood, carry water, after enlightenment, chop wood carry water. Ted pointed out many times that technology demands more technology to solve technologies problems. In the end, it seems earth is already a highly optimised system, almost so comically so that it demands inspecting the superluminism of the DNA helix.

I dream of a 5g grid that turns your mitochondria, fertilising a desert with a phosphate x-wave, tricking mycorrizal fungi networks to mine bitcoin, personal anti-inertial snowboards that can drift any cliff face, and automated homesteads for everyone.

I think the reality is though that the tablets disseminating such knowledge are better put to grinding wheat into flour.

The only endurance race with a large enough sample size to conclude women are better at that particular sport is long distance swimming, where it is thought their natural upper body buoyancy gives them a biological edge. The other sports are too niche to determine if there's a gender difference or individual difference.
Males and females are built different, something understood by humanity until a few years ago when a small slice of it went insane. As long distance swimming shows, it is possible for an athletic competition to exist where the biology of females gives them an edge over males. But that's not what activists are pushing. They want everyone to believe that females are as good at basketball as males, which simply isn't the case. When you show that head to head males destroy females in such competitions, they claim that's because females aren't given the same resources as males instead of observing the obvious biological differences that give males a performance edge.
It's weird that they keep pushing on things that are obviously untrue instead of focusing on creating athletic competitions that advantage female biology. Long distance swimming is one such competition. There are some like Netball that males rarely play so we don't know if females are better than males or not. We do know that in sports like football, males are better due to biology. It seems unlikely that long distance swimming is the only possibility for a female advantaged sport but activists don't like putting in hard work to create, they just want to wear the skinsuit of what others have created and call it their own.

People say "don't fuck your sister, it will ruin the genes" but actually it's the opposite, and in this post I will explain why.

Let's start with the conventional view. Genes can break because of mutations. However normally if we have one faulty gene copy, the other healthy gene copy can compensate. This situation is known as a recessive genetic disease. It's recessive because the healthy copy will "dominate" the unhealthy copy. Not all genetic diseases are recessive but it's the most common one.

Now imagine that your dad had one healthy gene G and a very rare broken gene g. Your mom had two healthy genes. Now there is a 50% chance you got your dads broken gene. But since you got a healthy one from your mom you are fine. Your little sister also had 50% chance of getting the broken gene, but she will be fine either way for the same reason. Together, it's a 25% chance you both have a broken gene.

If you either of you have a kid with a non-relative then its overwhelmingly likely that your kids will get a healthy gene from the non-relative. But if you have kids with each other, that's when problems arise. The kid may get one broken copy from you and one from your sister, leading to a sick child.

Now imagine there is not one such broken gene but several. Suddenly there may be big risk of issues.

So as promised let's turn this on its head.

Consider again what happens in the above scenario. The broken gene is masked which lets it proliferate.

But now imagine yourself fucking your cute sister. If the healthy genes combine then the broken gene has been eliminated! Success! If the broken genes are combined and the child has issues, then the child will be less able to pass the broken gene on! Partial success! However it may still happen that a child gets one broken and one healthy gene. This means that although the bad gene is selected against, it still has some chance of slipping through.

This is why fucking your sister leads to better genes in the long term!

I think inbreeding and outbreeding (such as race mixing) are both bad for us although in different ways.
the effects of close inbreeding are just more acutely visible. while outbreeding leads to disturbing disconnects and ,maladaptations and eventual infertility or proneness to disease.

I favour the intermediate level which seems to reflect a sort of tribe level relatedness and leads to optimal relatedness and fitness
