Since 2015 there’s a paper that has absolutely eaten me alive, neuron by neuron. It’s called “Using space and time to encode vibrotactile information: toward an estimate of the skin’s achievable throughput (Eagleman, Novich)” and causes my mind to be absolutely paralyzed by possibilities. Sensory substitution! What a thought, Eagleman!
& now, Elon Musk continues to seek talent for up-&-coming Neuralink – which promises to offer high-bandwidth brain-to-computer interfaces. Hm. Not a bad idea, especially when you consider the therapeutic applications of existing brain-to-computer technologies.
To research or work on any of these technologies would be the opportunity of a lifetime, & I’d cancel pretty much everything in my life right now to pursue them if only I knew how. In the meantime the opportunity to sit back and learn is available & my cynical little mind is already shouting out some words of caution.
BRAIN-TO-COMPUTER-INTERFACES-ARE-NEVER-GONNA-HAPPEN!, says cynical brain
Well, nothing interesting that ever happened was ever-going-to-happen. New inventions are just crazy, that’s how it is!
(this back-and-forth arguing continues). The primary concern is whether or not a high-bandwidth brain-to-machine interface for general-purpose use would be a good thing. Musk & others are right when they say that a keyboard isn’t enough to transmit a certain amount of information back-and-forth. But is that enough to support the overall claim that as it relates to human beings using and interfacing with information technology, quality of communication is proportional to the bandwidth of the information being passed along? Childish idealism runs rampant in my thoughts now – I’d like to go to coffee w a clever human like Elon & ask them, ‘will the problems you foresee with AI actually be solved by brain-machine interfaces or will they be worsened? Will the malicious capabilities of technology be diminished if humans are more closely linked w technology?’ It seems even a pen and paper (even morse code!) are often not enough for humans to communicate effectively, promptly, or sufficiently. It leads me to wonder if the tech-augmented hippocampus & cortex, adorned with messy glued-on silicon chips, might not be a devastatingly unhealthy Matrix-esque nightmare of limbic slop.
That coffee date won’t be happening anytime soon so in the meantime I’ll have to scroll from afar & hope these technologies work, & serve the common good.
