This is a little off topic but maybe someone who knows more about this than I do can chime in and give me some links to studies on this: What is the possibility of creating a biological computational device and are there currently efforts to do so? To me it seems like rather than physically building computers out of processed materials, growing computers in labs might be much more efficient and more powerful. The human brain is an example of this (not lab grown, biological). Are there any studies that look into harnessing the power of biological computers? I mean, actually tapping into neurological pathways, giving input and receiving output?
