fMRI, GPT-1, and your brain

Scientists have found a way to decode a stream of words in the brain using MRI scans and artificial intelligence.

While not perfect, this is some seriously scary stuff.

FWIW the researchers themselves did recognize this…

Although it’s nowhere near being able to decode spontaneous thoughts in the real world, the advance raises concerns that, with improvement, the technology might mimic some type of mind reading. “Our thought when we actually had this working was, ‘Oh my God, this is kind of terrifying,’” Huth recalls.

Participants have to consent to being “read,” and there are ways to prevent the software from figuring out even the “gist” of what they were thinking.

Still, imagine if some nefarious criminal group (or governmental agency, if there is a difference) decided to force someone to consent to have their thoughts read.

Long distance.

Permanently.

It’s getting harder and harder to distinguish scifi from reality.

Researchers can now “see” you using WiFi

Interestingly, they position this advancement as progress in privacy rights; “In addition, they protect individuals’ privacy and the required equipment can be bought at a reasonable price,” they wrote.

If you’re not scared of tech yet, you should be.

The real danger of unregulated AI

February 27, 2023

“I’m less frightened by a Sydney that’s playing into my desire to cosplay a sci-fi story than a Bing that has access to reams of my personal data and is coolly trying to manipulate me on behalf of whichever advertiser has paid the parent company the most money.

“Nor is it just advertising worth worrying about. What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,” Gary Marcus, the A.I. researcher and critic, told me. “I think that’s already been a problem for society over the last, let’s say, decade. And I think it’s just going to get worse and worse.”

Bringer of Light, Chapter 38 (Part 2): United Mars Colonies — Cut the Tether (this time for good!)

February 4, 2023
MThomas

Concerned that the UA forces on Luna Base may use the quantum teleporter to send an unwelcome gift to the newly-declared independent United Mars Colonies, former Mars security chief Sergeant Major Hamels and former Artemis crew members Enoch Ryan and Brady Cooper attempted to disable the teleporter ahead of time.

Too late…

Cooper could sense the radioactive isotopes within the canister. The explosive materials could kill them and most of this part of the colony due to sudden decompression of the building’s atmosphere. Fine radioactive dust spread everywhere. If it reacted with the cobalt in the boxes around them, the resulting dirty bomb could poison half or most of the planet for years. Decades, even. Who knows how long it would last.

If anyone were around to care.

“Fly-boy, you sense that?”

“Yeah.”

“Let me try something.”

“You want the rifle?”

“The energy discharge will just set it off. That’s probably what they were counting on. Or hoping we’d try to disable it.”

“Or send it back,” Hamels said. “No doubt their end has a rigged signal to reject contact, which also would set the thing off.”

“Then there’s only one option.”

With a sigh, Enoch set the rifle down next to the console. “Coop, something tells me you need me to help.”

“You read my mind.”

“Not yet.”

Now it was Hamels’ turn to back away. “What are you both doing?”

“Sergeant Major, we need you to focus on maintaining the force shield.”

The geist sat down crosslegged on one side of the platform. Enoch sat down likewise across from him on the opposite site. They stared into the force shield, concentrating on the cylindrical container.

“What are you doing?!” Hamels repeated.

“Changing it to uridium,” Cooper replied.

Chatbots — Still not AI but still dangerous

December 13, 2022
MThomas

[ChatGPT] could teach his daughter math, science and English, not to mention a few other important lessons. Chief among them: Do not believe everything you are told.

https://www.nytimes.com/2022/12/10/technology/ai-chat-bot-chatgpt.html

They’re all the rage online. Type in a request for a description how two historical people who never actually met would respond to each other had they actually met, and the program will oblige.

They’ll cause all sorts of rage online, too, once the peddlers of incessant false news and innuendo realize what a bonanza they’ve stumbled upon.

You want an image of an event that never really happened?

No problem. A program can generate one for you. We can even call it “art,” for what that’s worth.

No, BIG problem, especially when it convinces the gullible that it DID happen.

2023 will tell 2020 and 2022 to hold its coffee.

Just what we all wanted, right?

Still, chatbots are not (repeat, NOT) true AI. Sorry, Google engineer who watched too much Ghost in the Shell. Chatbots repeat our very human bias. Repeatedly.

As in, there are way too many racist, sexist, xenophobic, homophobic, and transphobic comments online. Full stop.

At a minor level, as a writing instructor, a student telling a chatbot to write a 600-word comparison-contrast essay is the least of my worries.

For starters, the damn things are probably scouring the Internet right now and “learning” from text on web pages like…uh…this one…

mRNA and nanotech? Stay skeptical and use the Baloney Detection Kit!

June 25, 2021
MThomas

It’s becoming increasingly common to see social media posts claiming that the mRNA COVID-19 vaccines, which include those made by Pfizer and Moderna, could alter a person’s DNA. Some posts even suggest that nano-machines are being injected into the body.

https://cosmosmagazine.com/health/covid/technically-no-longer-human-can-mrna-covid-19-vaccines-meld-with-your-dna/

Yeah, I’ve seen some of these posts. Talked to a neighbor who was convinced Bill Gates was trying to inject us all with a chip to control our minds.

Is there any truth to these rumours? Could an mRNA vaccine be modifying your DNA?

No.

(Read the linked Cosmos article for more details!)

Actually, all you need to do is use logic and reasoning, apply some critical thinking, and demand lots of science-based evidence.

It’s called the Baloney Detection Kit and was introduced in a Cornell University undergraduate course about critical thinking and the scientific method by astrophysicist Carl Sagan.

In his book The Demon-haunted World, he lays out nine steps to bust BS and call out unscientific baloney. I use it with my second year undergrad students in a current news and global issues course.

The link above to the kit also outlines some of the most important logical fallacies to avoid, with number 8 and 9 being the most difficult to explain and convince people about (because they involve education about basic statistics).

So will this convince anti-vaxxers who make outlandish claims online?

Probably not. Unless it goes viral 😉.

Bringer of Light, Chapter 21: Transit to Ceres

June 19, 2021

Just before leaving Luna, Weng stumbled upon evidence of a conspiracy. But just who is behind it and for what purpose, he doesn’t know. Yet.

“Sam, I’m not entirely sure what you are talking about.”

Weng tapped a finger against his chair. In the other hand, he held a microchip.

“If my suspicions are correct,” he said, “this holds an encoded message from somebody on the Ceres Mining Council to a certain Captain on Luna Base.”

After a moment, Gen took the chip. He examined it.

“What makes you say so?” he asked, expressionless. “More importantly, what does this have to do with us?”

Weng gestured at the shuttle’s command console. “Just read it. I’m sure with your expertise you’ll have no problems breaking the code.”

Gen nodded. He gently inserted the chip into the side of his pad, then soundlessly tapped at the screen. His eyes scanned the text. “Sergey,” he said finally.

“Sergey,” Weng agreed. “What does the message read?”

“As you suspected, it is a request for support.”

“What kind of support?”

Gen scanned the message. “Odd. There are few details.”

“Few?”

“None,” Gen admitted.

He passed the pad to Weng, who swiped down a page.

“Few?” he repeated, cocking his head. “This seems pretty obvious to me. ‘The Council will reward you for your service once the new administration is in securely place.’”

“As I said, there are few details. We do not know when, who, or how this will occur.”

Weng tapped the pad. “That hardly matters. This is damning evidence of an attempted coup.”

“Perhaps. Yet there is no way to prove who sent it”

“I can make a couple of guesses.”

He felt silent. He would hate for one of his guesses to prove accurate. But a nagging thought remained. How much did Riss know, if anything?

“Sam,” Gen said. “We must not delay. This message is at least three days old. Luna must be warned.”

“It’s not Luna I’m that worried about,” Weng replied with a smile. “It’s Ceres.”

“Oh?”

“Look at the relay information. There, just below the coded text. You’ll find that it was bounced off Ceres, and before that Zedra.”

“How would you know that?”

“Logic,” Weng said. He scratched the harness keeping him secure in the shuttle seat. At times like this, he would have preferred the ability to pace. No room in such a small ship. Also, no gravity.

He grimaced briefly, then smiled again.

“Weng, there is no need to—”

“Mind-reading still has its limits, I see,” Weng said without a trace of irritation. “And yet it is still irritating.”

“Sam…”

Weng ticked off his fingers. “First, who has the means to start a coup against a well-fortified base such as Luna? The UA, which occasionally includes China and occasionally does not, and the Slavic Confederacy are too invested in their Earthside territorial conflict to waste resources on an assault.”

“You seem sure of that.”

“As long as the UN controls the Mars Colonies, the Lunar Base is needed to keep the Colonies supplied,” Weng reasoned. “Depriving the Colonies of food and materials would endanger settlers from all Earthside city-states, not just an opponents. Too risky.”

“Well,” Gen said. “The Greater Indian Empire, then.”

“No. They have never shown any interest in conquest. They might, of course, try to render Luna inoperable as a supply relay center, so as to force a return to the use of the ISS for such purposes. But if so, why would they refuse to allow settlers to resupply at ISS? That makes no sense.”

“Hmm. So, that leaves only one option.”

“Yes,” Weng agreed, with a heavy voice.

“The Ceres Mining Council.”

“Maybe. To what degree the Council is implicated remains to be seen. The message could have originated with a Hunter. Or a Miner. Or even from someone on Mars.”

Gen fell silent.

“Which do you think it was, Gen?” Weng asked. His companion’s sudden quiet manner disturbed him. He vainly struggled to keep his thoughts buried, his emotions flat. Gen turned as if to speak, and suddenly Weng realized from this angle that Gen resembled Martin Velasquez very, very closely.

His father? Or…?

Gen frowned as a message scrolled down the console screen. He gestured. “Sam.”

Weng leaned over. He read the text, then sat back.

“It appears that at least one of your suppositions has already been proven incorrect,” Gen said. “The UA is on the way to Luna. In force.”

“Well,” Weng said. “What’s that famous phrase?”

“‘The die has been cast’, I believe.”

Three days to Mars, Weng thought. He hoped there was still a colony left standing when they arrived.

“Gen,” he said. “How far to Ceres?”

“At our current rate, we will barely arrive at Mars in time.”

“Mars can manage for another day or two. If we swing past Ceres, we may be able to stop a war.”

Gen paused, then stabbed at the console for a few moments. “There. I have input a new path for Ceres. But it will be futile in the end, Sam.”

“Why? Isn’t it worth it if we can prevent lives from being lost?”

“No,” Gen said, sadly shaking his head. “It wasn’t supposed to be this way. This wasn’t our agreement.”

“Our?” said Weng. He suddenly caught his breath. Gen.

“Yes,” Gen said. “We caused this. But we only wanted a place for our own. Luna was not meant to be affected. One of the hunters must bear a grudge.”

“So,” said Weng softly. “I was correct about you, from the beginning.”

“Yes,” Gen nodded. “I am, indeed, a clone. Martin Velasquez is, indeed, my father.”

“Then you are also Martin.”

“In a sense. But enhanced with additional DNA from other sources.”

“And who is ‘we’? With whom did you make an agreement?”

“That,” Gen said, returning his attention to the console, “is something you will find out soon enough.”

Weng sat back, thoroughly demoralized. Ah, Riss, he thought wistfully. I should have pinged you when I had the chance.

“Don’t worry, Sam,” Gen said, hands dancing over the console. “Riss will no doubt be here soon.”

Weng opened his mouth, then closed it. There was little point in asking how Gen knew that. He obviously was being used by all the players in this game. He, himself, lacked the knowledge to be a full-fledged player.

All he wanted now was to be with Riss. As he had planned. On Mars.

“Ironic, in a way,” Gen commented. “My name in Japanese means ‘original’ although I am but a copy. And yet thanks to my father’s careful engineering — and expense — I likely feel much greater sympathy than he ever will.”

He turned to Weng with a serious expression on his face. “Sam. Here’s what I want you to do.”

SpooQy-1 action at a distance!

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” says Aitor Villar, lead author of the study. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”

OK, OK, so it’s not the first time quantum entanglement has been demonstrated. But it sure is the smallest. Only 20 cm by 10 cm!

Now we only need a few thousand of these things and a way of somehow making tangled photons actually carry encrypted messages…

(Sorry, thinking of the SF novel I should have published by now…still figuring out the last two chapters!)

See more at New Atlas (note: I seriously doubt the CubeSat actually looks like that picture when it’s doing its thing).

Artificial intelligence-created medicine to be used on humans for first time

“This year was the first to have an AI-designed drug, but by the end of the decade all new drugs could potentially be designed by AI.”

Philip K Dick would have had a field day with this. Imagine what will happen once we start ingesting nanobots…

I, for one, welcome our AI drug overlords.

US phones come with preinstalled Chinese malware

January 9, 2020
MThomas

One of the pre-installed apps, which looks and operates as a wireless update program, automatically installs more apps without user consent, according to Malwarebytes.

And it appears to be a variant of Adups, malware previously traced to China, which transmits text, call-location and app data to a Chinese server every 72 hours.

China is so far ahead of the US in terms of hacking and spyware. And this is only the stuff that they didn’t even bother hiding…

Btw the image used is a repeat from a 2018 article about Lebanon-based spyware installed on phones in five different countries.

Missile strikes are distractions. The next war will be online.
