There's a fascinating (in my opinion) TED talk about this featuring the same Biologist, with examples of regenerative experiments performed using Flatworms: https://www.youtube.com/watch?v=XheAMrS8Q1c

This is Michael Levin, same guy from the article.

So, in other words, if this technology pans out, this could be possible https://mortalkombat.fandom.com/wiki/Goro

This implies that your brain could handle 4 arms. Chances are they would just be dead limbs.

So I wonder how much brain power (if any significant) is being taken up by the uterus during pregnancy.

Didn't Robert O Becker also explored this space?

Yeah, AFAIK Becker's "The Body Electric: Electromagnetism and the Foundation of Life" is pretty much all there was until Michael Levin came along and picked up the torch. IMO it's one of those weird "holes": why so little interest in human tissue regeneration?

Because there’s no immediate and clear plan for a return on the investment due to how speculative things are, private funding is scant. Because we (the USA) are spending most of our money on the insane military complex there is little extra public funding for actually beneficial R&D.

Edit: grammar.

Not really. You would need some training but as long as the limbs nerves are connected you can manipulate them.

I don’t think that’s necessarily true. We have mirrored nerve bundles dedicated to limbs with specific junctioning in the CNS. I don’t think it’s just brain plasticity at play, it’s fundamental wiring structure from limb to brain as well.

I have seen several podcasts with Michael Levin now and it is really brilliant work he and his team are doing. For what it's worth he also comes across as a really nice guy.

I (and many others, I’m sure) had the pleasure of listening to him on the Lex Friedman podcast. I’ve listened to that episode three times, I really enjoy it. Not only did he discuss his research, but he also dips into the philosophical domain - connecting electromagnetic communication between cells to philosophy of the mind and the self. I don’t know what that itch is, be he scratched it.

This technology doesn't seem to be limited to existing limbs and organs. After replacing a missing arm you could add a third arm. A man could grow a uterus since he has the X chromosomes and with a transplant that includes Y chromosomes, a woman could grow testes. Parthenogenesis could become a choice. Another head seems possible. The limits are more likely to come from regulation than a reluctance of people to trans…

If only they would make a sequel! I don't understand why that game was poorly received.

So now the scientific community accepts chi. About time. The reality of bioenergy is obvious to anyone who's practiced chi kung or experienced their chakras.

No. What's being discussed here has nothing to do with the pseudoscience of chi or chakras.

OMG here we go with the marginalization term "Pseudoscience". Stereotyping things you don't understand doesn't make you a smart person.

One sex could decide it no longer wants to deal with anyone not of their sex and wipe them out. Humanity could go on with the artificially created sex organs. Lots of possibilities, not all of them the fun, wild and crazy anything goes utopia some are looking for.

We're seeing how the west is discovering those "chakras" and unlike the east, where the understanding of this topic is very broad and fuzzy, due to lack of experience in most cases, the west will develop a very narrow, but very sharp knowledge. Pair that with the thick dark cloud of nihilism enveloping the west today, and it's not hard to see where this will end up. Levin seems to have discovered what the east calls…

Can you explain what you mean by "a very narrow, but very sharp knowledge"
