Bottlenecks, small population inbreeding, genetic drift, founder effect, etc
Basically what happened was, an alt-group of African humans decided earth was not safe anymore and its collapse was imminent -- they need to get to Mars. But since they don't have a way to get a spaceship in Africa, they will need to leave Africa and do whatever is necessary to build one, including throwing the people who helped them under the mammoth if need be.
At this point they have a pretty diverse gene pool and represent the humans well. They walk for a bit but came upon some steam vents and decided take a break and steam some food and enjoy the ocean view in the distance. The leader is not happy they stopped for food or rest. Later they are shooketh awake just before fire rains down on them. 3/4th of them make it safely to the ocean, and what luck the water is receding it'll be easier to cross, for the first 2/3rds at least. The tsunami gods demanded a toll and claimed the back 1/3. Not happy with the direction of leadership, half the group decided they could establish a better foundation away from these clowns and forked themselves.
Meanwhile, back in Africa and finally having got rid of that crazy mars dude and his cult followers, they decide to invite all the neighbors to an epoch swinging dance party to celebrate -- complete with the best plant-based party favours they could dig up/gather. Thus, ensuring the larger African population and their descendant would end up with an abundant supply of pokemon variants to swap between'em.
Though, you may want to take a look at the linked paper above for a more precise explanation. I may have paraphrased a bit.
It's been cynically suggested that certain prestigious schools are primarily social clubs for the children of the rich and powerful, and that the schools let in some academically excellent students to confer an aura of merit around the ruling class. :)
Sometimes, sometimes just optical, but in any case, there's even a guy, Ken Sherriff, who has been doing this as a hobby for ages. It's not like this is merely theoretical.
It's not that you're utterly wrong; some transformations are irreversible, or close to. Multiplying each pixel's value by 0, assuming the result is exactly 0, is a particularly clear example.
But others are reversible because the information is not lost.
The details vary per transformation, and sometimes it depends on the transformation having been an imperfectly implemented one. Other times it's just that data is moved around and reduced by some reversible multiplicative factor. And so on.
TSMC has not committed to a US plant that applies their most advanced technology. Currently, they are going to produce chips with larger slower features, some generations behind their state of the art -- that's commercially very useful, and a good idea, but in no way replaces the state of the art chips that they produce in Taiwan. Alas.
That's not just an analogy; impedance is index of refraction, with the same body of modern theory, except that "impedance" derives from the history of analysis of low frequency ("radio") waves whereas "index of refraction" derives from the history of analysis of high frequency ("optical") waves.
Specifically, physics papers concerning research based on particle accelerator experiments always have hundreds or even more.
It doesn't minimize the research; that sort of thing just requires a lot of participants. But it does imply a lessening of credit per contributor, aside from the lead investigator(s).
Why stop at two? X seems to just be crazy person x says crazy thing y, so no problem adding that to my dns blacklist, fb and insta are as you say, just as obvious as tiktok. SEO results are dominated by AI vomit blogs, nothing to see there so searech engines are useless. LLMs seem to be mostly ok for finding things right now, I'm sure they will figure out how to mess that up soon enough though. YouTube is really useful for figuring out how to fix my <insert thing broken in my house>. But other than that is just the prototype the other stuff was based on. For news I look at news sources that cost money, wsj, economist etc. because then there is at least a chance that I myself am not the product. For finding music I ask local musicians who they like and follow those referrals a few deep. For seeing funny pet antics I look at my pets. To learn more about tech I come here and follow links.
Unlike TikTok, X is an American social media platform. By default, It is protected under free speech rights. TikTok is Chinese and doesn't get to play that card. End of story.
That doesn't keep them off my dns blacklist though. Seems like whatever card tiktok played was good enough to get tomorrow's administration to change course.
If the Democrats field a candidate that is willing to debase themselves with a stupid dance that goes viral, I feel there may be a change of heart. Assuming Trump doesn't manage to run for a third term.
