Brain-computer interfaces (BCIs), invasive or non-invasive, have projected unparalleled vision and promise for assisting patients in need to better their interaction with the surroundings. Inspired by the BCI-based rehabilitation technologies for nerve-system impairments and amputation, we propose an electromagnetic brain-computer-metasurface (EBCM) paradigm, regulated by human’s cognition by brain signals directly and non-invasively. We experimentally show that our EBCM platform can translate human’s mind from evoked potentials of P300-based electroencephalography to digital coding information in the electromagnetic domain non-invasively, which can be further processed and transported by an information metasurface in automated and wireless fashions. Directly wireless communications of the human minds are performed between two EBCM operators with accurate text transmissions. Moreover, several other proof-of-concept mind-control schemes are presented using the same EBCM platform, exhibiting flexibly-customized capabilities of information processing and synthesis like visual-beam scanning, wave modulations, and pattern encoding.

Near future ?

Good luck creating an interface that doesn’t require calibration which can easily be thwarted by simply being non-compliant.

To even use a BCI with an incredibly simple UI such as a screen with only text characters takes tens to hundreds of hours of training and message transmission is quite slow (in this study about 12 characters per minute). This is because brains aren’t all built the same, and the very idea that you could decode brainwaves into digestible thought that another human will understand without willful participation of both parties is a long, long way out.

You might be able to create a generalized AI/ML model trained on tens of thousands or millions of participants in BCI (which wouldn’t exist until BCI became mainstream and we had large datasets for sale) but even that would be quite easy to thwart with simple noncompliance for a solid 10+ years of research. Eventually we’d probably be able to decode even that, but simple techniques such as meditation could easily thwart appropriate calibration in the presence of noncompliance.

Naturally they require a calibration, currently still quite complicated, but in a few years this will surely be unnecessary with the advancement of AI and quantum computers. Not so long ago a 1 Mb hard drive weighed half a ton. Apart from all this calibration it sure isn’t that big of a deal, if you use this in interrogations, also a current lie detector requires a calibration of around half an hour. Current technological advances are exponential

I understand your concern, but I think you are underestimating just how different one human brain is from another. There’s a reason brain connectome research has moved so slowly and that’s not even trying to compare one human to another, that’s just trying to understand the basics of an incredibly complex and incredibly varied set of systems which only nominally look similar.

I know that we still need to fully understand the human brain, but in view of the exponential scientific progress in recent decades, I prefer to refer to Clarke’s first law

By no means am I implying its impossibility, I’m simply stating we’re further from the future you fear than you think. We almost certainly will destroy ourselves via global warming first.

I think on the contrary we are closer to the future we fear. Governments are becoming more and more radical, taking away one basic right after another, we are on the verge of a world war with a huge amount of money invested in weapons and science in products that are used for military use. Regarding climate change, yes, we are almost at the point of no return and this means future catastrophes that are going to cost very many lives, that is, a warming of more than 2º of the average temperature in the coming decades. That is, if we continue down this path, we would not even experience the consequences of global warming, we will have Mad Max much sooner.

If you have a corrupt government that wants to put you in prison then it will always find an excuse to do so whether you broke any law or not. So, I’m not really too worried about that particular application of the technology.

Agree, I’m just against making it even easier for them. If this technology exists, it won’t be long before government forces will also use it ‘to fight crime’. Although this technique can be a blessing for people with disabilities, it will not take away from the other. It is in most of the good inventions like this, that they also led to abuses. and this can also be a blessing for the secret services, according to them, also to do good, avoiding waterboarding and electroshocks.

Every technology can be abused in some way. I think it’s a red herring to focus on technology when the problems are inherently sociological.

Naturally, also a non-stick pan can serve to sink someone’s skull. But I think that the risk in an invention that allows access to people’s thoughts runs much more risk of being abused, for this it is too succulent for certain groups.

I really don’t think this makes much of a difference in practice.
