I know about the recent stuff using DNA as a storage medium. I am interested in writing a story where humans have mastered everything Evolution has to offer; a time when technology is completely integrated into a vivarium/Bioregenerative Life Support System like ecosystem on multiple levels.
I’m looking for references to better speculate about organic compute as a complete replacement for silicon in a very distant future.
I came here to make this comment. The Edenists, a genetic fork of humanity, have created sentient machines through biotech. Some of the large space habitats are grown with a layer of neural cells a metre thick - in a cylinder shell that may be 30km long, totalling cubic kilometers of brain matter. Super-intelligent space buildings.
