Many engineers, including me, think that some time around 2050, we will be able to make very high quality links between the brains and machines. To such an extent that it will thereafter be possible (albeit expensive for some years) to arrange that most of your mind – your thinking, memories, even sensations and emotions, could reside mainly in the machine world. Some (perhaps some memories that are rarely remembered for example) may not be suited to such external accessibility, but the majority should be. The main aim of this research area is to design electronic solutions to immortality. But actually, that is only one application, and I have discussed electronic immortality a few times now :
What I want to focus on this time is that you don’t have to die to benefit. If your mind is so well connected, you could inhabit a new body, without having to vacate your existing one. Furthermore, there really isn’t much to stop you getting a new body, using that, and dumping your old one in a life support system. You won’t do that, but you could. Either way, you could get a new body or an extra one, and as I asked in passing in my last blog, what will your new body look like?
Firstly, why would you want to do this? Well, you might be old, suffering the drawbacks of ageing, not as mobile and agile as you want to be, you might be young, but not as pretty or fit as you want to be, or maybe you would prefer to be someone else, like your favourite celebrity, a top sports hero, or maybe you’d prefer to be a different gender perhaps? Or maybe you just generally feel you’d like to have the chance to start over, do it differently. Maybe you want to explore a different lifestyle, or maybe it is a way of expressing your artistic streak. So, with all these reasons and more, there will be plenty of demand for wanting a new body and a potentially new life.
