Preparing for AI-enabled cyberattacks

Posted by in categories: business, cybercrime/malcode, existential risks, information science, robotics/AI

MIT Technology Review Insights, in association with AI cybersecurity company Darktrace, surveyed more than 300 C-level executives, directors, and managers worldwide to understand how they’re addressing the cyberthreats they’re up against—and how to use AI to help fight against them.

Cyberattacks continue to grow in prevalence and sophistication. With the ability to disrupt business operations, wipe out critical data, and cause reputational damage, they pose an existential threat to businesses, critical services, and infrastructure. Today’s new wave of attacks is outsmarting and outpacing humans, and even starting to incorporate artificial intelligence (AI). What’s known as “offensive AI” will enable cybercriminals to direct targeted attacks at unprecedented speed and scale while flying under the radar of traditional, rule-based detection tools.

Some of the world’s largest and most trusted organizations have already fallen victim to damaging cyberattacks, undermining their ability to safeguard critical data. With offensive AI on the horizon, organizations need to adopt new defenses to fight back: the battle of algorithms has begun.

Humans Were Apex Predators for Two Million Years – Our Stone Age Ancestors Mostly Ate Meat

Posted by in categories: evolution, existential risks, food, genetics, military

Researchers at Tel Aviv University were able to reconstruct the nutrition of stone age humans.

In a paper published in the Yearbook of the American Physical Anthropology Association, Dr. Miki Ben-Dor and Prof. Ran Barkai of the Jacob M. Alkov Department of Archaeology at Tel Aviv University, together with Raphael Sirtoli of Portugal, show that humans were an apex predator for about two million years. Only the extinction of larger animals (megafauna) in various parts of the world, and the decline of animal food sources toward the end of the stone age, led humans to gradually increase the vegetable element in their nutrition, until finally they had no choice but to domesticate both plants and animals — and became farmers.

“So far, attempts to reconstruct the diet of stone-age humans were mostly based on comparisons to 20th century hunter-gatherer societies,” explains Dr. Ben-Dor. “This comparison is futile, however, because two million years ago hunter-gatherer societies could hunt and consume elephants and other large animals — while today’s hunter gatherers do not have access to such bounty. The entire ecosystem has changed, and conditions cannot be compared. We decided to use other methods to reconstruct the diet of stone-age humans: to examine the memory preserved in our own bodies, our metabolism, genetics, and physical build. Human behavior changes rapidly, but evolution is slow. The body remembers.”

Neuralink Co-Founder Says We Have the Tech to Build an Actual Jurassic Park

Posted by in categories: existential risks, genetics, neuroscience, sustainability

For the uninitiated, “Jurassic Park” and “Jurassic World” make up a five-movie franchise — with a sixth in the works — all based on Michael Crichton’s hit novel about how bad of an idea it was to open a place like Jurassic Park. Leveraging recent advances in genetic research to create entirely new creatures is certainly an enticing idea, though there’s a big difference between something potentially being feasible and actually being a good idea.

But it’s not all fun and games when you’re playing god and creating new dinosaurs. Hodak later added that de-extinction could be a valuable tool for increasing biodiversity, perhaps because we find ourselves in the midst of an era of mass extinction.

“Biodiversity (antifragility) is definitely valuable; conservation is important and makes sense,” Hodak tweeted minutes later. “But why do we stop there? Why don’t we more intentionally try to generate novel diversity?”

OSIRIS-REx to make final close approach to asteroid before heading back to Earth

Posted by in categories: asteroid/comet impacts, existential risks

WASHINGTON — NASA’s OSIRIS-REx spacecraft will make one final close approach to the asteroid it collected samples from next week before heading back to Earth.

On April 7, the spacecraft will pass 3.7 kilometers above the location on the asteroid Bennu called Nightingale where, in October, the spacecraft briefly touched down and collected as much as several hundred grams of material, now stored in the spacecraft.

Immediately after that sample collection maneuver, the mission had no plans to return to the vicinity of Bennu. However, NASA decided to make a final pass over the touchdown site to see what changes the sampling made to the Nightingale region, like the creation of a crater.

Particles of a Meteor Explosion From 430,000 Years Ago Found Hidden in Antarctic Ice

Posted by in categories: asteroid/comet impacts, existential risks, particle physics

Approximately 430000 years ago, a meteorite exploded over Antarctica.

The only reason we know about it now is because scientists have just found tiny, once-molten particles of space rock that have been hidden away in the ice ever since.

Based on an analysis of those particles, the event was an unusual one — not quite powerful enough to produce an impact crater, but nor was it a lightweight. The jet of melted and vaporized material that blasted from the mid-air explosion would have been more hazardous than the Tunguska event that flattened a Siberian forest in 1908.

Asteroid collision ruled out for 100+ years

Posted by in categories: asteroid/comet impacts, existential risks

A collision between Earth and the asteroid 99942 Apophis can be ruled out, for at least the next century, based on new observations by NASA.

Collective Superintelligence Summit (Early Bird)

Posted by in categories: existential risks, robotics/AI, singularity

Your Survival Depends On All Of Us — Support Open Sourcing Collective Superintelligence Basically, the point of the summit is Artificial Superintelligence or ASI is coming eventually. There are groups of organizations discussing the existential risk that ASI poses to humanity. Even if we only develop an AGI, AGI will still create ASI and we lose control at some point. Supporting the Open Sourcing of Collective Superintelligent systems is our only hope for keeping up and moves us forward before other technologies outpace our ability to keep up. Please support our Summit and help decide how to open source a version of the mASI (mediated Artificial Superintelligence) system, and the creation of a community-driven effort to make these systems better and better. Attendance helps to raise enough money to cover the costs of support services, cloud infrastructure, and the digital resources needed to get this open-source project up, covering publishing and support costs, while also making people aware of it. Papers and formal thinking also are really needed. This particular field of collective intelligence is poorly represented in terms of scientific papers and we hope this project can bring more prominence to this possibility of helping humanity become more than what we are and strong enough to contain AGI while we ourselves are able to become smarter and move to full digitization of humanity for those that want it. Then we can contain ASI safely and embrace the singularity. Please help, save yourself and humanity by support the Collective Superintelligence Conference. Sign up and attend here:

This is the early bird sign-up for the virtual summit held June 4th from 6 am PST to 4 pm PST via Zoom and Youtube. Speakers and Panelists, and workshops will be held in Zoom, and streaming will be done via Youtube.

NASA’s Planetary Defense: “Potentially Hazardous Asteroid” Predicted to Safely Pass by Earth on March 21

Posted by in categories: asteroid/comet impacts, existential risks

The interplanetary interloper won’t come closer than 1.25 million miles to Earth, but it will present a valuable scientific opportunity for astronomers.

The largest asteroid predicted to pass by our planet in 2021 will be at its closest on March 21, providing astronomers a rare opportunity to get a good look at a rocky relic that formed at the dawn of our solar system.

Called 2001 FO32, the near-Earth asteroid will make its closest approach at a distance of about 1.25 million miles (2 million kilometers) – or 5 1/4 times the distance from Earth to the Moon. There is no threat of a collision with our planet now or for centuries to come.
