Imagine guys like Musk, Bezos, Zuckerberg or Thiel cloning themselves. That's 100% dystopian. We would never be able to get rid of madmen! Power corrupts and makes the powerful just weird and unable to make rational decisions. That's why people in power need to be replaced regularly to have a stable society.

Re: The first early human eggs from stem cells
#112I am worried about the long term impact of research involving human conception, IVF, etc. The reason is that genetics/evolution don't yet seem to fully explain how humans exist. A computer genetic algorithm run for a billion generations doesn't lead to anything anywhere near the the complexity of a human. I suspect there are as-yet undiscovered effects which shape the next generation. Whether that be DNA methylation,…

#113I'd be very curious how they even define "safe enough" for this. With most therapies, the risk is mostly to the patient. Here the risk could be passed on to a future person who never consented to the experiment.

It's not so much a mitochondrial transplant, as it is fertilized egg nucleus transplant. Not just mitochondria are used from the third donor but their whole egg (sans nucleus). So unless a human might develop from a bat egg just from swapping out nucleus, which I'm sure it's not the case, super-powered batman must remain a fantasy.
Oh, so that's what you were aiming for, LOL there are many reasons for this chimera not to be viable, mitochondria co-evolves with the nuclear DNA, you can't just take a mitochondria from a totally different species

Can you point me to anything about mitochondrial transplants? I'd love to see bat mitochondria transplanted into other mammals. They must have really superior ones given the energy expenditures needed to support flight and their long lifespans.
I don't, isn't this the recipe to get IRL Morbius?

> We have not ended up with "humans which aren't as strong, aren't as smart, aren't as well adapted to a changing environment, etc." Haven't we?
Objectively we’ve only become smarter (IQs have increased), stronger (fitness records continue to be broken), etc. since infant mortality shrank. If you believe otherwise please provide evidence.

I think this is decisively the wrong way to think about it. Yes, layering hypotheticals like that means that any one scenario is extremely unlikely to be the thing that gets you, but that doesn't mean the shape of the problem is wrong. It's like arguing with someone who doesn't believe in using seat belts when driving. "Why should I put them on?" they say, and when you try to explain what might go wrong they won't li…
The history of humanity, I say of hominids even, was defined by humans playing it unsafe - migrating, sailing, inventing bombs, you name it. We played god before even we invented gods, and reached this point in time. Should we say "this is best we can do, let's stop everything"? Nah, not likely.

I don't know man, people basically aren't having sex already. The fertility rate is way below replacement in all modernized countries, half of gen Z has never had sex at all, contraception is free, people struggle to get pregnant the more chronically ill the population gets, and the people who actively do want to get pregnant are going to want to use whatever technology there is to improve things.
But outside the bible, who says we must be more and above replacement rates? Is such a tragedy for humanity if there are only 4 billion humans in 100 years? 4 happier billions? It doesn't HAVE to go up all the time, and between extinction (zero humans) and overcrowding (X billions) there are many unknown ways to go.

#120Currently, egg retrieval is a significant part of the IVF process - one that's notoriously taxing on the women. Once this gets refined enough for clinical uses, it can become as simple as "take a blood sample once, produce as many eggs as you need". With an added benefit of being able to get eggs when traditional retrieval fails.
