Brain-computer interfaces (BCIs) have captured global attention, particularly since humanity\u2019s uber-entrepreneur Elon Musk jumped on the bandwagon by founding Neuralink Corporation in 2016. Herein, I explore the already existing interface between humans and computers which, thanks to one of the brain’s most astonishing properties, has augmented our minds for decades already.<\/p>\n\n\n\n

The possibilities the most modern BCIs offer are beyond revolutionary: they range from curing the incurable to augmenting humans to unprecedented levels of functionality \u2014 they are pushing the neural frontier. The advances in BCIs are powered by ever-improving AI algorithms and computing capabilities making progress in this field wholly unpredictable. Alas, these overwhelming opportunities come with serious ethical, societal, and economic risks. This article will tell a story about the advent of BCIs, their opportunities and risks, and the convergence of mind and machine toward merged consciousness. Finally, it will outline how we must prepare to ensure human autonomy and how policymakers can safeguard our future. Before that let\u2019s briefly talk about our brains and why they are so astonishing.<\/p>\n\n\n\n

Neuroplasticity and neurofeedback: how machines augment the mind<\/h2>\n\n\n\n

I decided to spend this winter in a warmer climate so that I could focus on improving my golf swing, training on my bike, and my professional endeavors away from the dread of Northern Europe. Navigating my new surroundings wasn\u2019t a big deal, Google and Apple Maps guided me in my car or while working out on my gravel bike. At first, the apps were my constant guides, but after a few days, I didn\u2019t need them anymore. I knew the main routes and where to avoid congestion with my car and the most exciting paths to speed along with my workout bike. The apps taught me through a human-computer feedback loop \u2014 feedback from the apps created new neural connections in my brain. What would have taken weeks without computers, I accomplished in days thanks to computer augmentation! So, how does a computer augment the brain without physical connectivity? The answer lies in the brain\u2019s incredible adaptability \u2014 neuroplasticity<\/em><\/strong>.<\/p>\n\n\n\n

\n

<\/p>\nNeuroplasticity is the brain\u2019s ability to reorganize itself by forming new neural connections enabling us to adapt and learn. How do we learn? We learn by trial and error, feedback from our surroundings and our brain teaches us what and what not to do, e.g. don\u2019t touch the hot stove, sugar is pleasant, detergent isn\u2019t, picking this up will invoke mum\u2019s anger and so on. This response to our actions \u2014 so-called neurofeedback \u2014 facilitates learning, the formation of neural connections. Meanwhile, there is clear scientific evidence for this: In \u201cThe Brain That Changes Itself<\/a>\u201d, Norman Doidge<\/a> highlights the work of Dr. Merzenich<\/a>, a neurologist, with patients suffering from tinnitus. Using neurofeedback and targeted auditory retraining, the therapy successfully altered the brain\u2019s maladaptive neural activity patterns responsible for the condition. Medical evidence, including brain scans, showed a reduction in overactive neural pathways demonstrating the power of neuroplasticity for recalibrating the brain.<\/em><\/cite><\/blockquote>\n\n\n\n

Ultimately, that is what the navigation apps have done with me: They gave me (neuro-)feedback on my navigation which accelerated the process of me internalizing my new surroundings \u2014 the human-computer interface in action! Computer augmentation isn\u2019t limited to navigating new surroundings: in my professional work, I utilize computer simulations to understand complex systems. By interpreting simulation outputs, I understand these systems better in a shorter period of time; yet again what would have taken years without computers, I can accomplish in days with the help of the silicon machines. The same is true for, students learning new skills on Coursera<\/a> or Udemy<\/a>, holidaymakers brushing up on their language skills on Babbel<\/a> or Duolingo<\/a>, or engineers using computer-aided design (CAD) \u2014 see photo below. Thomas Malone refers to this as \u201csuperminds\u201d, people collaborating create intelligent systems that are more intelligent than the sum of their parts; meanwhile, computers not only facilitate this collective intelligence by enabling easy information exchange but also contribute to the system by providing information that is used as feedback1<\/sup>.<\/p>\n\n\n\n

These examples highlight a simple yet profound point: computers have been augmenting the human mind for decades, they give us feedback that enables us to form new neural connections more rapidly. Computers facilitate neuroplasticity through neurofeedback<\/em><\/strong>. Even without direct connections to the brain, learning and decision-making are facilitated, and computers have become integral to how we navigate the world, learn, and create! The collective intelligence of humans collaborating was converted to a supermind by computers. While they have long been part of our cognitive toolkit, the gap between humans and computers is narrowing faster than ever \u2014 mind and machine are converging.<\/p>\n\n\n\n

The human-machine interface: a shrinking gap<\/h2>\n\n\n\n

Not long ago, a computer was something in an office or in certain homes. Since the development of the first real smartphone, the iPhone<\/a>, most of us have carried a mini computer with us at all times. While these systems remain separate from our physical bodies, the gap is narrowing rapidly. Wearables<\/a> like smartwatches or fitness trackers have brought us closer to the realm of computers; they monitor functions such as heart rate, heart function, blood oxygen levels, sleep patterns, and more. All this comes with significant benefits as we can monitor our health or sports performance while receiving feedback on it. Again, we can improve our health or sports performance based on input from computers. Personally, I own a smartwatch, EEG breast strap, bike computer and sensors that allow me to monitor my training and observe short- and long-term improvements. The system is also safeguarding me, e.g. when cycling a steep ascent, the system warns me when my heart rate goes into a dangerous zone. However, these clearly beneficial possibilities come with clear data privacy concerns as all the data are submitted to the cloud and analyzed by the providers’ AI. These data privacy concerns were and are addressed successfully2,3<\/sup>.<\/p>\n\n\n\n

Things are getting interesting when we directly interact with our brain: Non-invasive devices such as Muse<\/a> and Mendi<\/a> have made neurofeedback treatment available at home. Again, these devices are connected to a smartphone and provide the data to the service provider\u2019s cloud. These devices are unidirectional \u2014 i.e. they cannot affect our brain, just read some of its signals.<\/p>\n\n\n\n

Bidirectional and invasive BCIs have been in use in medicine since the 1990s, Deep Brain Stimulation<\/a> (DBS) for instance is a blessing for people suffering from Parkinson’s disease<\/a>. While primarily stimulating the brain and alleviating Parkinson’s symptoms instantaneously, modern DBS systems can also record neural activity for adaptive responses that improve symptom relief. Notably, progress is rapid in this area and one specific device has received significant media coverage and will hence serve as an example \u2014 Neuralink<\/a>.<\/p>\n\n\n\n

\n

<\/p>\nNeuralink aims to create a seamless BCI capable of both recording and stimulating neural activity to treat neurological disorders, restore sensory and motor functions, and eventually enhance cognition and communication. Unlike medical DBS, which typically uses 4-8 electrodes for broad stimulation, Neuralink employs up to 1,024 flexible, high-precision electrodes to enable detailed, bidirectional communication with individual or small groups of neurons, allowing for significantly more complex and scalable applications \u2014that\u2019s more than100 times the touch points with the brain! Neuralink is hence the prime example that human and computer are converging.<\/em><\/cite><\/blockquote>\n\n\n\n
