Above: the species of Big Brain fish may become an ideal candidate for the transfer of digital consciousness from human to fish.
Human Brain Transfer to Alternate Species
By the time human brain digitization becomes possible, the first experiment to transfer a human brain into an alternative species will happen. AI will decode not only the human brain but that of many other species, animals, fish, etc.
Take for example fish. The sub-parts of a human brain can be transferred into the fish, less the non functional brain centers for speech etc. A human mind in a fish may become highly valuable, able to explore vast underwater regions for survey, monitor shorelines for military submarine invasion, study underwater phenomena and the Andreas Fault Line, and provide a plethora of marine data.
Developing a new aquatic AI species with some qualities of a jellyfish may be another possibility to explore the ocean, linking it to a digitized human brain
Likewise, a human brain transferred into a monkey could provide data to explore the Amazon Jungle or other forests.
Way out on the cutting edge of the technology we may find special transformations of brain to become more compatible with plants and insects.
