“The world’s first living robots have been built using stem cells from frog embryos, in a strange machine-animal hybrid that scientists say is an ‘entirely new life-form.’”
There was no evidence that the disembodied pig brains regained consciousness. However, in what Sestan termed a “mind-boggling” and “unexpected” result, billions of individual cells in the brains were found to be healthy and capable of normal activity.
“These brains may be damaged, but if the cells are alive, it’s a living organ,” says Steve Hyman, director of psychiatric research at the Broad Institute in Cambridge, Massachusetts, who was among those briefed on the work. “It’s at the extreme of technical know-how, but not that different from preserving a kidney.”
The “mini brains” were technically “cerebral organoids,” made from the cells that make up the region of the brain known as the cerebellum. They started out as clusters of stem cells raised in a special medium designed to support brain development, eventually growing into organoids with a similar structure as a real-life cerebellum.
This paneudaimonia looks like the opposite of panpsychism.
“Paneudaimonia is the idea that the whole universe is absolute pleasure, except in the domain of what we know as sentient beings, in which all experiences imply different types of suffering.
Paneudaimonia is the idea that identity, and / or the “I” and / or consciousness are generated and / or are linked to suffering or pain. That is to say, that the self-consciousness is always painful. But the non-conscious experience (the not self-consciousness) is always pleasurable.
According to the idea “Paneudaimonia”, every time we experience something positive or pleasant, it is because we are losing self or identity; and when we experience the self or the identity, we experience it in a painful way.”
“Organoid” is the term generally used to refer to a small ball of human cells grown in cell culture from stem cells (human stem cells for human organoids). The stem cells may be embryonic stem cells, induced pluripotent stem cells, or other types of stem cells, but the effort has been to get cells that will all become one or more cell types found in an organ. Thus, there are human liver organoids, kidney organoids, gut organoids…and yes, brain organoids. The human neural organoids have been grown for over three years – and some of them have survived for over two years. They have diameters of about 4 millimeters (or a sixth of an inch), about the size of a very small pea. They have no vasculature and so the cells need to be in contact with the oxygen and nutrient bearing (and waste bearing-away) culture media. Currently human neural organoids have about two to six million neurons (no other brain cells so far, just neurons). They self-organize, grow synapses, fire, and continue to get more and more complex as time goes on. Still, by comparison, the human brain is estimated to contain approximately 86 billion neurons.
Chimeras – in this case, human/non-human brain chimeras – are creatures with some human brain cells and some non-human brain cells. (Thus far, in brains at least, they are always non-human animals with some human cells, not humans with some non-human cells.) Chimeras have been used in research for many years, though organoids are opening new possibilities: such as transplanting human organoids into rodent brains – which turn out to grow blood vessels for them.
Researchers have also long used human brain tissue kept alive outside the body – ex vivo tissue – but what is used and how is, like chimeras, becoming “new and improved.” Instead of keeping flat sheets of human brain cells alive in a dish, researchers are keeping alive and studying larger and larger chunks of human brains, taken from neurosurgical discards or from the recently dead. There are even some efforts, so far only in non-humans, to keep whole brains from dead animals “alive” apart from their bodies.
“Using DASH, the Cornell engineers created a biomaterial that can autonomously emerge from its nanoscale building blocks and arrange itself – first into polymers and eventually mesoscale shapes. Starting from a 55-nucleotide base seed sequence, the DNA molecules were multiplied hundreds of thousands times, creating chains of repeating DNA a few millimeters in size. The reaction solution was then injected in a microfluidic device that provided a liquid flow of energy and the necessary building blocks for biosynthesis.”
“If we want to develop a sentience simulation project, that admits as many hypotheses and theories about sentience as possible, we will find that obviously in such an environment it will not be enough to represent the sentience alone, but surely we will have to include other types of substances that may be related to it. To give a very simple example, if we consider that sentience emerges from a wet biological animal material brain, and we want to represent a living frog that feels in our system, the simulation environment must support the representation, in one way or another, of at least two types of objects or concepts: material objects (such as the frog’s brain or whole body and the physical environment where it lives) and sentient objects (such as the frog’s experiences).
Because of this, when simulating sentience, elements that are not purely sentience should generally also be simulated; and if we want to have an environment that admits all possible hypotheses and theories about sentience, then to be very sure of leaving nothing out, it would be very interesting to be able to include as types of simulation objects all kinds of possible components of reality according to all kinds of paradigms, theories and beliefs.”
A quote from Max Planck:
“All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.”

What is Max Planck talking about? Consciousness? Sentience? Panpsychism? God?
This is a list of situations, projects or initiatives in which there could be an “astronomical” (huge) reduction in the amount of suffering compared to what currently exists or is expected. Many of these situations (but not necessarily all of them) involve a high risk in the sense that they are difficult projects whose probability of success is very low. In some cases, this may happen because they are projects that assume as certain some hypotheses for which there is little evidence, so we can consider them unlikely, although not impossible.
I insist that the only criterion to appear on this list is that the project or idea supposes an astronomical reduction of the suffering that we believe exists or will exist. The list can include both remote possibilities and speculative approaches as well as conventional and highly probable scenarios.
The following is a list of types of suffering organized according to their uncertainty.
1. Suffering well reported.
In this case, the suffering being is typically an adult human who survives to the negative experience and can describe it.
2. Suffering difficult to survey.
It is the case of suffering in non-human animals, very young humans, humans in oppressive situations, humans with some cognitive impairment, and humans who do not survive the experience of suffering, or for any other reason they cannot communicate it.
