Computers of the future will be built not by factory machines, but by living cells such as bacteria. Scientists ‘have described how wires can now be made by yeast organisms, and how solar panels could be built using substances produced by sea sponges. Researchers believe these kind of technologies will be essential if we are to continue to shrink the size of electronic devices.’ But ‘Computers made with these natural processes are not just around the corner — it will be many years before the technologies can be developed that far.’

While scientists think about small sizes and environmental benefits, I also think if it would be possible to implant such bacteria for additional computational power in human brains — just in case we have to upgrade them.
