One day it may be possible to vascularize these organoids to increase size/volume, remove waste products, provide nutrients, promote internal cell viability, and increase gas exchange.

within the organoid. shaker methods only promote gas diffusion thru approximately 200 microns of tissue. This leaves organoids that are greater than 400-450 microns in diameter at risk of increased core cell death. i think future vascularized organoids could promote greater gas exchange and possibly reduce internal core cell death.

Have your ready any papers about ghost organs? Basically they decellualrize a heart for example and all thats left is the extracellular matrix. I'm curious if they could decellularize a brain feed nutrients through the vasculature of the brain and then recolonize the brain with neural stem cells

Burning question? Did you try using these tiny brains for computation? Could be very interesting to see a little blinking LED controlled with a tiny brain.

Can you test if those brains have consciousness by attaching organs like eyes or nose or ears to them?

They are organoids, not whole brains, too small to develop consciousness. To build bigger organoids (closer to the size of the human brain) you have to solve the problem of how to feed the cells deeper. In mammals this happens using a circulatory system that feeds them using blood. The researchers working on organoids haven't achieved this yet. If they try to build bigger organoids the cells inside die because they don't get any oxygen or nutrients.

Probably lots of benefits like treating brain injuries, dementia, etc. among one of the many treatments that could support increased healthspan We start reaching unethical lines when there's sentience (which would be very hard to do despite organoids having the hardware for consciousness because consciousness does not equal sentience)

imagine when they can make full human brains, they will literally become brains in a vat.

Can you please make a big brain much bigger than a man's like a super big brain and then we could connect brains of all the people (on a voluntary basis) to this biggest brain and this Brain you made will have billions of eyes, ears, and micro-services(our human brains) and become a more advanced consciousness altogether.

This could have big clinical implications. Pathways and mechanisms involved in the difference between different species are likely also involved in differences within a species - especially when comparing brains of primates (which are genetically very similar).

The conscience is hard to explain, especially the part of any living thing that is responsible for tracking of time and dimension (ik it's a completely different thing, ignore that if you want, but I hope your brain wants to learn). Yet we cannot jump to conclusions right away. Saying it was a higher being is like quitting, believing what was said, but if you want to reveal an answer, you must ignore that temptation of saying it was a God or Creator, and to keep on searching even if it seems impossible. From a standpoint of an atheist, God could have been a being that some person wrote in so that people can use him as someone to put the responsibility onto. Someone to be there when you are alone, because the brain has convinced itself of such a feature in this world. The contrasting effect, though, can be found darker and more menacing, for relaxing is the barrier between us and discovery, for in some cases, relaxation is giving up and letting go. It's as if the brain is challenging itself via this aspect of the imagination. Otherwise, if you are a religious member of society, then you can say that God (or whoever you see as fit creator) is challenging you to not give up. He's telling you to "give it a try and see how thigs are," but if you don't want to, he'll become the answer for you.
