Immortal Mind Uploading

Mere mortal body has to die, but what of mind? Brain transplants are defeated by mortal neurons, that will all eventually age and fail. Uploading minds to robot super computer brains, is immortality's holy grail. For conscious mindful robot bodies can become the new mankind. Abandoning frail mortal flesh to dust in grave, or ash in smoke, consigned. You can replace your robot host with the latest model each year, for an image refresh and tech upscale. Your mind downloaded from brain to computer can be uploaded, again and again, full-scale. The mind-file then can then live forever, immortal mind to replaceable robot body, uploaded and maligned. But what would it be like to live inside a metal box forever? With metal arms and legs covered in fake skin, denied the thrill of flesh, Without the sensual joys of touch and feel, of imbibing food and drink, and all other such pleasure. Would a life immortal in a tin can be worthwhile, even with regular robot refresh? Despite all the simulations, gadgets, fake this and that, would this really be the answer? Or is mind so tied to mortal body that a senseless mind, immortal in computer chip, could never really mesh?
