>1945 was a long time ago and a very different Japan Japan is currently sanctioning Samsung because it wants to avoid responsibility for WW2 sexual slavery.

That's a horrendous mis-statement of a convoluted political issue. Japan has no sanctions against Samsung directly, they are upset that materials they export to South Korea keep showing up in North Korea, while SK denies being the cause. There's a separate case which was decided in SK courts claiming in short that Japan should give SK more reparations, because of course a court is going to consistently find in favor…

This is flat out bullshit. Photoregist, hydrogen fluoride, fluorine polyimide are all together mainly used for photolithography/OLED. It is not a coincidence.

It is very obvious that Japan targeted Samsung and their primary goal is to ruin the Samsung and hynix's(SK semiconductor industry) business, ultimately to harm SK economy(semiconductor industry is significant to SK economy). They do this because of the recent SK courts' verdict and Japan don't like to admit nor apologize horrendous war crimes they committed in WW2.

Just repeating Japan's specious pretexts(that to avoid potential WTO issues and get plausible deniability) that they are doing this because of NK is disingenuous.

How does the human part affect cognition? A stem cell for example is before it "decides" to be a specific cell right? If that is the case in terms of embryo development, then how do they coax only specific cells in embryos to only express themselves in parts of the body excluding the brain. Complicated but I really am not understanding some basic principles here.

Yes you are missing basic parts. There are certain genes that produce proteins that then bind to other control areas of the DNA that affect how much other genes are expressed. These last genes translate to proteins that make e.g. a pancreatic cell what it is. But this is a tree of increased specialization on which embryonic stem cells become e.g. blood stem cells which then specialize to rbc, white platelet producers.

Wouldn't we still have slavery if we did things the way you suggest?

That would very clearly negatively affect the opposing party.

If you have slavery, obviously you're not going to care much whether the slaves oppose it.

I hoped technology would reduce animal exploitation. It does in some areas, like cell farming to create food without animals. And synthetic models for pharmaceutical research. Maybe this branch of research can evolve to eliminate animals as well.

Looks like we're moving in that direction for some things with organ on a chip systems: https://en.wikipedia.org/wiki/Organ-on-a-chip

It wasn't pacification. It was a nation collectively coming to terms with their brutal past and taking to heart the phrase "never again". If "not bombing non-knee-bending nations on a whim" equals "pacified" in your mind, then I hope you never hold a position of power in any government.

I'd imagine Japan's attitudes have changed the same, as well.

I'd be interested in knowing if that's true, and if so, to what extent. My knowledge of Japanese culture - especially modern prevailing attitudes towards the Japanese government's actions in the second world war - is very limited. I'm not qualified to speak to that.

When I heard Alex Jones on Joe Rogan saying that there was human-animal experiments being made I thought he was exaggerating. In my opinion this kind of research crosses some ethical lines that shouldn't be crossed. If one considers an embryo as an independent life, what species the embryo belongs to? Wouldn't be the ones in this experiment half humans with human rights? After all, the scientist doesn't know all, and…

I saw you had been downvoted and I upvoted you, despite disagreeing very strongly with your opinion, because you stated your opinion without vitriol and while I might disagree I'll still fight for your right to say it as long you do so in a way that isn't hurtful. I think the line of inquiry into replacement organs can be researched ethically but the how of the research may cross ethical lines if not done carefully.…

I knew I would be, but its fine. Thank you for your words! I share the same belief regarding freedom of speech.

About the research, I hope I am wrong and the advances that came out of it help save lives and extend the human life. I just wish they take those ethical questions in consideration too.

If significant % of the population doesn't think it's problematic it should be allowed as long as it doesn't influence lives of the other part. You can easily opt out of any stem cells based research or treatment, we can make it not state funded. Opposing that is the kind of self-righteous aggressive morality I despise. It's the same with abortion: about half the population thinks it's ok to let a woman decide. It do…

Wouldn't we still have slavery if we did things the way you suggest?

Slavery kinda influences lives of slaves. Maybe.

Well, if you're allowing abortion on the basis that an embryo isn't human life, you're by extension allowing this.

Right, that's what I am saying. If even that discussion isn't settled yet, we should be more careful and wait before mixing humans and animals.

The discussion is very settled in a number of countries. I assume Japan is one of them.
