What is Brain Computer Interfacing, why is it relevant in 2023, and how will the future of it pan out? The term’s almost self-explanatory, but it’s the concept behind establishing direct communication between the brain’s electrical activity and an external device. The field has mostly been experimental, being researched with some practical applications – though it’s a buzz in the world of neuroscience. This invention has given individuals with severe motor and neurological disabilities to control computer cursors and restore communication and motor function to a limited extent. In the last year, we’ve seen the emphasis on the field grow due to its potential in medical interventions, virtual augmentation/reality and the gaming industry. This rapid advancement is signalling a future where the lines between human cognition & technology continue to be blurred.

However, Elon Musk’s Neuralink, a neurotechnology company, has been the subject of a lot of attention in the field due to its recent controversies. Their activities have ranged from the reveal of their tests being involved in welfare violations by causing the deaths of 1,500 animals to Musk’s ambitious claims of “[curing] tinnitus in 5 years”. However, this declaration should be taken with a grain of salt, considering the billionaire’s notorious track record of overpromising on deliverables.
Most recently, Neuralink gained FDA approval for human testing, despite remaining under federal investigation. Regardless of how this experiment pans out, this will likely further advancements in the field, which will ultimately hasten the ongoing AI & technological singularity. It’s likely that as developments are made, and BCI tests on neuromorphic hardware components prove successful, over the decades we’ll see more commercialised uses. For now, though, BCIs suffer from a low transfer rate of data and if an overall lack of market-ready/user-friendly electroencephalogram acquisition devices continues, it’s unlikely that we’ll see them in the short term future.
However, it’s worth considering what societal implications this technology may lead to in decades to come. Once internet accessibility is implemented, how will the education system navigate the challenge of someone readily having access to any resource at a mere thought? How will sports such as chess change if the perfect move can be thought of in seconds? Finally, with the skill ceiling of so many manual tasks lowered, will we see a mass job displacement and a shift in demand for those who produce creative media?
Heralding a new age of interface between humans and machines, Brain-Computer Interfacing offers more than just an intriguing technological prospect. The discourse surrounding BCI is far from being a mere footnote in scientific history; instead, it encourages a broader discussion about our ties to technology, our moral obligations, and our outlook on tomorrow.
The development of BCI has faced a set of technical impediments and societal issues, and yet its advances epitomise our willingness to challenge the boundaries that lie ahead of us. Only time will show the effects of this remarkable technology on society, but it holds great promise amidst high stakes. However, one thing is for certain:
The conversation has only just begun.
