Unlocking Minds or Inviting Danger? The Pros and Cons of Brain-Computer Interfaces

We’re so busy with “Can We” that we don’t ask “Should We”

In the realm of science fiction, the idea of melding the human brain with advanced technology has long been tantalizing. Today, this notion is becoming closer to reality through the concept of “Brain-Computer Interfaces” (often referred to as BCIs). The idea is simple : translate brain signals into physical outputs. Among the most notable ventures in this field is Neuralink, co-founded by our Lord & Saviour Elon Musk. His (overhyped) company is developing implantable (invasive) brain–machine interfaces, with a chip implemented directly into the user’s brain. But there are also plenty of non-invasive methods being trialled.

Mastering neural signalling (which serves as the brain’s communication method) would allow us to create a direct link between the brain and a variety of external devices such as phones, cars, robots… the list goes on. Imagine being able to move a cursor, send a text message, or do a Google search with just a thought. This will be revolutionary in many (if not most) fields. However, as with any groundbreaking technology, brain-computer interfaces present a complex mix of benefits and challenges that necessitate careful examination.
