Yuli Ban is talking about the prediction and emergence of generative AIs, the extent to which those can disrupt humanities reliance on creativity and productivity. He mentions ‘the dead internet theory’ that postulates that most content is autogenerated, obfuscating the actual people using the internet and reducing their actual exposure.

I think we already see this in social media, internet forums and other areas where fake content and profiles are detected. and this can spread to youtube and short form video platforms, telemarketing and scams. as well as use by political groups and states.

Yuli also mentions the long term implications — peaking human population and the notion of Transhumanism where humans merge with an infinitely more capable AI which assumes control. he mentions how biology is a quality many would like to preserve, to varying degrees.

Everyone is now scrambling to integrate AI with as many facets of human life as possible. Neural nets and machine learning can offer greatly improved processing speeds, yet these aspects still rely on digital pathways that may never fully mimic the biological structure of the human brain. The next step in AI improvement would be to combine the best of both the digital world and the biological world. Some scientists are already experimenting with this possibility, as a new article published in the academic journal Frontiers of Science is deep diving into the realm of biocomputers and organoid intelligence (OI).

All AI applications today rely on computing power provided by powerful CPUs or GPUs. OI, on the other hand, is seeking to bring “unprecedented advances in computing speed, processing power, data efficiency and storage capabilities” by harnessing the complexity of lab-grown cell-cultures repurposed from adult skin cells that consist of 3D clusters of neurons and other brain cells.

Tiny insects known as sharpshooters excrete by catapulting urine drops at incredible accelerations. Their excretion is the first example of superpropulsion discovered in a biological system.

Saad Bhamla was in his backyard when he noticed something he had never seen before: an insect urinating. Although nearly impossible to see, the insect formed an almost perfectly round droplet on its tail and then launched it away so quickly that it seemed to disappear. The tiny insect relieved itself repeatedly for hours.

Trying to make computers more like human brains isn’t a new phenomenon. However, a team of researchers from Johns Hopkins University argues that there could be many benefits in taking this concept a bit more literally by using actual neurons, though there are some hurdles to jump first before we get there.

In a recent paper, the team laid out a roadmap of what’s needed before we can create biocomputers powered by human brain cells (not taken from human brains, though). Further, according to one of the researchers, there are some clear benefits the proposed “organoid intelligence” would have over current computers.

“We have always tried to make our computers more brain-like,” Thomas Hartung, a researcher at Johns Hopkins University’s Environmental Health and Engineering department and one of the paper’s authors, told Ars. “At least theoretically, the brain is essentially unmatched as a computer.”

Is self-consciousness necessary for consciousness? The answer is yes. So there you have it—the answer is yes. This was my response to a question I was asked to address in a recent AEON piece (https://aeon.co/essays/consciousness-is-not-a-thing-but-a-process-of-inference). What follows is based upon the notes for that essay, with a special focus on self-organization, self-evidencing and self-modeling. I will try to substantiate my (polemic) answer from the perspective of a physicist. In brief, the argument goes as follows: if we want to talk about creatures, like ourselves, then we have to identify the characteristic behaviors they must exhibit. This is fairly easy to do by noting that living systems return to a set of attracting states time and time again. Mathematically, this implies the existence of a Lyapunov function that turns out to be model evidence (i.e., self-evidence) in Bayesian statistics or surprise (i.e., self-information) in information theory. This means that all biological processes can be construed as performing some form of inference, from evolution through to conscious processing. If this is the case, at what point do we invoke consciousness? The proposal on offer here is that the mind comes into being when self-evidencing has a temporal thickness or counterfactual depth, which grounds inferences about the consequences of my action. On this view, consciousness is nothing more than inference about my future; namely, the self-evidencing consequences of what I could do.

There are many phenomena in the natural sciences that are predicated on the notion of “self”; namely, self-information, self-organization, self-assembly, self-evidencing, self-modeling, self-consciousness and self-awareness. To what extent does one entail the others? This essay tries to unpack the relationship among these phenomena from first (variational) principles. Its conclusion can be summarized as follows: living implies the existence of “lived” states that are frequented in a characteristic way. This mandates the optimization of a mathematical function called “surprise” (or self-information) in information theory and “evidence” in statistics. This means that biological processes can be construed as an inference process; from evolution through to conscious processing. So where does consciousness emerge? The proposal offered here is that conscious processing has a temporal thickness or depth, which underwrites inferences about the consequences of action.

“Computers that run on this ‘biological hardware’ could in the next decade begin to alleviate energy-consumption demands of supercomputing.”

Johns Hopkins University researchers have outlined plans for a “bio-computer” that is highly feasible in our lifetime.

“Computing and artificial intelligence have been driving the technology revolution, but they are reaching a ceiling,” Thomas Hartung, a professor of environmental health sciences at the Johns Hopkins Bloomberg School of Public Health and Whiting School of Engineering, who is spearheading the work, said in a statement.

An updated metric for prioritizing species’ conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness, has been published on February 28 in the open access journal PLOS Biology, authored by Rikki Gumbs from the Zoological Society of London (ZSL), U.K., and colleagues.

In 2007, ZSL established the Evolutionarily Distinct and Globally Endangered (EDGE) metric to prioritize species for conservation based on preserving evolutionary history embodied within endangered species. The approach allocates each species a score based on the evolutionary distance, measured in millions of years, that separates a species from its closest living relatives, and its conservation status in the IUCN Red List.

EDGE has since been applied to mammals, amphibians, birds, sharks and rays, corals, and flowering plants, and is used to allocate conservation funding. To update the EDGE metric to incorporate recent advances in evolutionary biology and conservation, ZSL hosted a workshop for conservation scientists and practitioners, who reached a consensus on EDGE2—an updated metric that includes the extinction risk of closely related species and uncertainty in species’ relationships and conservation status.

Water is a vital resource, and clean water is a necessity. Texas A&M University researchers have developed a new technique to monitor one of the key processes of purifying water in real time.

Raw water contains microscopic pathogens that are too small to remove during water and wastewater treatment easily. Chemicals are added to form large clumps called flocs, which are easily filtered out. Flocculation is the process used in water treatment to remove suspended particles from the water.

“Coagulant chemicals need to be added to purify drinking water and remove turbidity (cloudiness) and microbes that are too small to be visible to the naked eye,” said Dr. Kuang-An Chang, professor in the Zachry Department of Civil and Environmental Engineering at Texas A&M.

We’ve known about telomeres for more than 80 years, but these tiny, protective structures at the end of the chromosomes keep revealing secrets to us, including the possibility of having surprising functions.

It turns out that these key biological cogs can produce proteins, something previously thought impossible due to their simplicity.

While it’s not clear yet what these proteins might do, the fact that they exist at all is significant.
