Some creatures are able to regrow lost limbs (like crayfish, salamanders, starfish and some spiders). As humans, we are not as advanced in that department. But we can create such limbs – conventional prosthetics – artificial limbs or organs designed to provide (some) return of function. Some replacements, like glass eyes, don’t even provide that – they don’t see better, they simply look better. But a new wave of smart prosthetics is busy changing all that.
Bionic eyes are surgically implanted, and connect with retina neurons, recreating the transduction of light information back to the brain – so the brain can once again ‘see’. Bionic lenses provide augmented abilities, enabling eyes to see three times better than ‘perfect vision’. Bionic eyes will have all the abilities of modern visual technology like night vision, heat sensors, distant, infra-red and x-ray vision - and other augmented abilities. Likewise, other prosthetics will become smart, enhancing the human experience with enhanced reality.
The latest innovation in prosthetics is the revolutionary addition of machine learning and AI. Here, the wave of change is going to be of tsunamic proportion. Bioengineers are impressively pushing into this frontier, merging the human experience with superhuman abilities. The new field of development is the power of ‘smart brains’ – or neuro-mechanical algorithmic collaboration - where artificial intelligence, machine learning, and the human brain interface to create a brand-new human experience.
Neuro-mechanical algorithmic collaboration may sound like a huge tongue twister – but you already know what it means. Let’s parse it. Neuro- (of the brain), mechanical (of machines) algorithmic (all information, human or machine, is processed by way of algorithms) collaboration (working together). These BMIs (Brain Machine Interfaces) will become the norm of our future. What does that look like? The end result is the human brain having access to any and all information instantly, being able to share it with others seamlessly, and interpolating it into the situation appropriately.
For instance, a doctor in the middle of a surgery observes an unexpected bleed, instantly pulls up in his brain the last 20 occurrences of that bleed in similar situations, and is able to select the best cause and solution. Or you and I could have this conversation brain to brain, without the use of telephones or devices - simply using brain to brain communication. While that seems like a huge concept, in one sense it is not very different to what we do all the time. We use technology – the cell-phone – to communicate thoughts from one brain to another brain. Imagine if we could use technology to negate the need for the cell-phone. That is brain to brain communication.
There is a rat in a cage in Duke University, USA. In front of him are two glass doors that cannot open. He has a probe in his brain that links to a computer. In Brazil, there is another rat with a similar probe in his brain. In front of him are two wooden doors that he cannot see through. Then place a treat behind one of the glass doors in front of the rat in the USA, and his brain tells the rat in Brazil which door to open. That is brain to brain communication. Remove the probe (go wireless) and we have innate brain to brain communication.
There are many, many challenges before this can become a functional reality – but it is within sight. Amongst the biggest challenges are mapping the human brain sufficiently so we know what neurons to fire up, and creating a broad enough wireless connection to relay the enormous amount of information required to transmit even a single thought. We are making progress. Elon Musk is one of the innovators in this field. He is currently suggesting he can make changes to the brain to address Parkinson’s, Alzheimer’s, Autism and other brain disorders.
Scientists can control the movement of a rat with a PlayStation remote type control, have it climb a ladder, jump off a ledge that is higher than it would comfortably jump from, then inject endorphins into the rat’s brain that made the jump feel good.
Who knows – perhaps the opportunity lies ahead to correct socially disruptive behaviour, or criminal thinking? Would that be more effective than incarceration? Who knows - perhaps couples will be able to release endorphins into each other’s brains to establish a sense of bliss? Who knows – perhaps we will be able enhance our brains so that our knowledge is infinite, our character impeccable, and our reality phenomenal? If so, we shall be able to create our own reality, a world in which we and others live in peace and happiness. We can have the life we want in the world we choose.
Who would not want that? Or would they?
