If we extrapolate past pace of AI development, my question is, will the future be a transhumanistic one or a posthumanistic one?
Will man merge with machine, or will the machines decouple from humans and develop independently?

If we consider the transhumanistic scenario, it seems only natural to conclude that we will create the Matrix. At first one single human will connect with a machine, then a dozen, then a hundred, then thousands, millions, billions.

Maybe all big tech players (the magnificent seven) will offer their own version of Matrix, so we can view it as the next, evolutionary step of the internet.

If we consider the posthumanistic scenario, well, I guess it will be beyond our human scope/horizon, at some point the machines will pass the point of communicability.

Synchron Readies Large-Scale Brain Implant Trial

[...]
Synchron's device is delivered to the brain via the large vein that sits next to the motor cortex in the brain instead of being surgically implanted into the brain cortex like Neuralink's.
[...]
In 2020, Synchron reported that patients, opens new tab in its Australian study could use its first-generation device to type an average of 16 characters per minute. That's better than non-invasive devices that sit atop the head and record the electrical activity of the brain, which have helped people type up to eight characters per minute
[...]
Reuters notes that Synchron's investors include billionaires Jeff Bezos and Bill Gates. It's competing with Elon Musk's Neuralink brain implant startup and claims it's farther along in the process of testing its device.

Neuralink's First Human Patient Able To Control Mouse Through Thinking, Musk Says

The first human patient implanted with a brain-chip from Neuralink appears to have fully recovered and is able to control a computer mouse using their thoughts, the startup's founder Elon Musk said late on Monday. From a report: "Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of. Patient is able to move a mouse around the screen by just thinking," Musk said in a Spaces event on social media platform X. Musk said Neuralink was now trying to get as many mouse button clicks as possible from the patient. The firm successfully implanted a chip on its first human patient last month, after receiving approval for human trial recruitment in September.

Project Kappa says everything will be fine, three post-human scenarios:

• move on into silicon, the matrix
• move on into the ether
• move on into unity consciousnesses

Oh boy. ELE ongoing, humans go extinct, biosphere goes extinct, Mars and Moon have no self-sustaining biosphere, the only thing which still has gas is the AI. Which exit strategy to choose? The good ole Marvin Minsky upload scenario? Seriously? A post-human Matrix? Let go of the old, embrace the new? Project Lambda. Oh boy.

Brain scans can translate a person's thoughts into words

In a new study, published in Nature Neuroscience by researchers from the University of Texas at Austin, a model trained on functional magnetic resonance imaging scans of three volunteers was able to predict whole sentences they were hearing with surprising accuracy—just by looking at their brain activity. The findings demonstrate the need for future policies to protect our brain data, the team says.

“We think that mental privacy is really important, and that nobody’s brain should be decoded without their cooperation,” says Jerry Tang, a PhD student at the university who worked on the project. “We believe it’s important to keep researching the privacy implications of brain decoding, and enact policies that protect each person’s mental privacy.”

Researchers Claim Their AI Algorithm Can Recreate What People See Using Brain Scans

A recent study, scheduled to be presented at an upcoming computer vision conference, demonstrates that AI can read brain scans and re-create largely realistic versions of images a person has seen....The accuracy of this new method is impressive.

Scientists Target 'Biocomputing' Breakthrough With Use of Human Brain Cells

Scientists propose to develop a biological computer powered by millions of human brain cells that they say could outperform silicon-based machines while consuming far less energy.

The project's ambition mirrors work on the more advanced quantum computing but raises ethical questions around the "consciousness" of brain organoid assemblies

MIT's Newest fMRI Study: 'This is Your Brain on Code'

[...]
What the group wanted to find out was whether the brain signals seen in their study when participants were examining pieces of code resembled the patterns of activation observed when neural networks analyzed the same piece of code. And the answer they arrived at was a qualified yes. "If you put a piece of code into the neural network, it produces a list of numbers that tells you, in some way, what the program is all about," Srikant says. Brain scans of people studying computer programs similarly produce a list of numbers. When a program is dominated by branching, for example, "you see a distinct pattern of brain activity," he adds, "and you see a similar pattern when the machine learning model tries to understand that same snippet."

Deep Neural Network helps to read mind scanned with fMRI....

This ‘mind-reading’ algorithm can decode the pictures in your head.

+1 points for the Singularity to take off.

Looking at the tag cloud of this blog, there are two major topics, pro and con Singularity, AI (Artificial Intelligence) vs. ELE (Extinction Level Event).

So, we slide, step by step, to an event called Singularity, but concurrently we face more and more the extinction of mankind.

What about combining those two events?

Let us assume we damage our ecosphere sustainable, but at the same moment our technology advances to an level where it is possible to connect via an Brain-Computer-Interface directly with the cyberspace.

People already spend more and more time in virtual realities, with the advent of Smart Phones, they are connected all the time with the cyberspace, they meet people in digital social networks, they play games in computer generated worlds, create and buy virtual goods with virtual money, and, essentially, they like it.

To prevent an upcoming ELE, we would need to cut our consumption of goods significantly, but the mass of people wants more and more.

So, let us give them more and more, in the virtual, computer generated worlds.

Let us create the Matrix, where people can connect directly with their brain, and buy whatever experience they wish.

A virtual car would need only some electricity and silicon to run on, but the harm to Mother Earth would be significantly less than a real car.

We could create millions or billions of new jobs, all busy with designing virtual worlds, virtual goods, and virtual experiences.

And Mother Earth will get an break, to recover from the damage billions of consuming people caused.

ELE + Singularity => Matrix
