there is one problem though, with doing 200 times at once, and the only metric to judge is a scam life clock

nothing makes the sci/philosophy cuck seethe more than determinism.

a choice must be either:

caused (determined)
not caused (random)

that's it. just like a number must be even or odd.
there's no third option - "free will" isn't even a coherent possibility.

if you think free will is a third option:
how is it not caused by anything but also not random?
how does it escape either having causes or not having them?
self-causation is impossible.

any counter argument runs into this inveitable wall of logic

therefore, I present you: The Inevitable Conclusion:

free will would require impossible self-causation

Is this possible, or is there some factor Land has not considered that is likely to halt the process? How long would speciation take on current trends?
I'm asking here, because it tends to be /lit/ or /pol/ who talk about this stuff, but they don't know the first thing about genetics. Would like to get the opinion of someone who understands biology.

>it'll be generation ships when it happens
This is also impossible. The humans who would need to keep a generation ship running are most likely not the same ones who will see their new home. Keeping such an "ark" running is filled with so many insurmountable variables involving radiation exposure, mechanical failure, accleration and deceleration, social systems, and the fragility of the human mind and spirit under pressure. Imagine a big prison flying through space for 150+ years where you cannot go outside and where even the guards aren't able to go home after their shift. It's pretty much unfeasible. We don't even know if humans can withstand the psychological toll of the 6 months journey to Mars. On your hypothetical ship many generations will be born, live and die during the journey. Will they even want to carry on the mission after they are many generations removed from the original crew who agreed to it? It's still unknown how to keep cosmic rays at bay without Earth's protective magnetosphere. NASA published research where mice were blasted with cosmic radiation. Result: massive GI damage and tumors. At this point, we're not even sure we can make it to Mars without giving astronauts cancer. Then either the planet at the other end is dead, in which case we'll have to spend centuries terraforming it (if that's even physically possible in any way), or it's alive, and its microbiome could kill us, or trigger chronic disease or allergies.

>Is this possible, or is there some factor Land has not considered that is likely to halt the process?
short ASI timelines would cut it off before it got far enough to count as speciation (something like speciation probably still happens in post-singularity world if beings like humans are still around, but it comes from different causes)

>>16488732
>how does random genetic drift occur?
As it turns out when you calculate the randomness per se of genetic mutations in species the effect is actually very very small. The internal randomness of the mechanisms of DNA replication cannot explain evolution by itself, i.e: I still remember when I did the calculations back then and taking the models and everything it would take an absurd ammount of time for simple mutations to change a species, that is why, you often hear that genetics is not everything, you have to account for the many things that are affecting the genetic make up of a species, which is why biology is so not deterministic, because when you actually try to make a prediction to the same level as say: the rotation of the Moon around the Earth, it is the whole universe which you have to control for.
>Weinberg Equilibrium not contradict the Wright effect?
Don't take weinberg equilibriums as law, it is just a model, between so many to understand biological systems at population level, you can use it to understand genetic drift against the ideal conditions of the weinberg equilibrium and make predictions or explain things based on it. That is why it does not contradict it, because it does not explain it just models it.
>a new ethic group?
I would go out on a limb(Land is hard to understand sometimes) and say that this is a new group of people in a completely different sense. The definition of an ethnic group is about culture, which is wide enough to encompass wealth and biological phenotypes. But the idea Land has is that such a group would have transceded human society so much that they would be different in all senses, these people are not even human so they don't even understand the world as other humans would do even if you were to strip some of their characteristics and make them live among other people in the same conditions, which is something you can do with mere rich people today.

NTA but the population trend isn’t known because they’re not an easy species to track population stats of. It’s not totally accurate to say they’re continually declining, but an increase of only 20,000 after a 50 year hunting ban is pretty bad recovery. In comparison humpback whales were only at around 5,000 in the 60s, and have since jumped to 130,000+ despite having way longer generation times. It’s possible they recovered more since the hunting ban and then started declining more recently with habitat loss, we can’t say

Schizophrenia is thrown about too often, parts of life are strange, and the birth of a idea is sometimes strange. It would be more suitable to call someone who thinks about reality in an incorrect way schizo but to have theories about reality that aren't normal don't really mean anything.

Why do I look so different then everybody? I find it peculiar and strange, I've tried posting my photo on different boards in threads where you guess a person's ethnicity and I barely get any replies, people avoid the topic with me. I get told different things. I've been told that I don't even look white. But the thing is nothing really fits.

I wonder, how often does uniqueness or rarity of features persist in a race? I don't have really angular features, my face isn't long or very big, like I'm not short but I'm not very big looking in general. I've been told I look indian and italian and I think I sort or have features and skin like he Indians, germanics, and even Japanese. My nose is not that big, it's not flat but it doesn't protrude for my face like it's covered by facial fat or something, a lot of people have protruding noses.

My theory is that my race all but almost went extinct and I am one of the last of my kind, but technically though I am northwestern European.

It's because of the way that the Weierstrass functions are defined.

this sounds like leibniz. i'm not sure you could literally just find-and-replace all instances of "monad" with "telor" in the monadology to get CTMU but the way you describe it sounds very similar.
>One would expect chemical properties to vary significantly depending on how many atoms there are in a clump as their telor density is lower and/or GOD may have not processed a given combination before and has to figure out how it works.
this is a retrodiction, not a prediction, we already know chemical properties vary based on chemical structure and our current theories have explanations of why. does CTMU give any predictions about the properties of new synthetic elements? what does it have to say about the island of stability predicted by our current theories?
