Is this meant to be some kind of "technically there are no privately controlled corporations in China because the state always has the last say on everything" argument? Well it's the same everywhere, the state always has the last say within its jurisdiction. For example, the US government can commandeer any company using the Defense Production Act, or any new law Congress might decide to pass

With few exceptions academia wholeheartedly refuses to talk about this subject and racial supremacists aren't exactly objective. Obviously we can be diverse in physical size and appearance. I'm more interested in IQ and temperament which have been proven to be at least partly influenced by genes.

Holy shit, based and same, I thought I was the only high iq chad back in high school who knew the redpill on drugs, lmao. I still haven't done any psychedelics yet though. How would they affect someone who's more or less at peace with themselves, and arguably egotistical to a flaw? I'm not a fat cuck like the redditor guy prior to his trip, and it's not like I strictly need any help in making notable lifestyle changes

you guys think all women are the same.
lower class junkie women love lower class criminal men.

these days everyone goes to college because of idea that its fair to give everyone the same privilege but you forget that a lot of the women are low born, it's in their genes to be sluts and hookers.
when those sluts who descended from hookers hook up with tyrone they're just following their programming.
you're not supposed to consider them your women

You cannot control making money unless you're a billionaire or a banker. As a dependent wagie you have no control over your money. As a crypto gambler you have even less control over your money.

I've got some stupid questions.

Is there any experimental proof of space expansion/hubble constant? or do we just assume it with seemingly linear redshifting of galaxies?

Why are there no live-feeds of orbiting satellites of other planets/moons? Is it because the shitty data transfer? Isn't the moon close enough for it to be possible? or is energy usage an issue?

I was watching Fox News's show Outnumbered and they were about to discuss this scientific news about how AI can make you believe that you're another person. Stupidly, OJ Simpson had to pass away at that exact moment and so they covered that instead of that news about AI... as if I give two fucks about that fat, old, washed up, murderer. It's a travesty because they never got to discussing that part about AI.

So I have no idea what they were talking about. Do any of you /sci/ people know anything about AI making you believe you're in somebody else's body?

Anddo you think there will ever be a day where we can transfer the conciousness of one person into another? Say you have a comatoes patient that is brain dead but with a healthy body and another patient who has a terminal illness and doesn't have much longer to live, could they transfer the mind of the dying patient into the comatose one as a sort of "body" donor progam?

And just for fun, if you could be anyone else other than yourself who would you be?

Your self-concept is constructed with feedback you get from interacting with others. In other words: you see yourself in the manner others relate to you. Since your interactions change your self-concept is always changing whether or not the others are AI.
