>>11546491I can't speak to "in silico" immortality since I know jack shit about developing microchips.
But in the field of biology, we don't fundamentally understand what causes aging. There are factors that are probably important (accumulation of epigenetic tags, oxidative damage, senescent cells and telomere shortening) but they're not the whole picture. And even if we did understand how those systems worked, we don't have the tools to do things like edit your genome/epigenome across all of your cells.
There are lots of things to be excited about in biomedical research, but I wouldn't count on 'immortality' happening any time in the next century. You'll get to enjoy a much longer and healthier life though, since science is actively winning the battle against cancer.
