At some point in the future, could an A.I. company manufacture something akin to a neural bridge, allowing ordinary people to occasionally share their experiences? Maybe. Elon Musk recently announced the founding of Neuralink, a company that aims to put A.I. inside the head, merging humans and machines. Neural lace, the artificial hippocampus, brain chips to treat mood and memory disorders—these are just some of the mind-altering A.I. technologies already under development. While it may not be around the corner, a device akin to a temporary neural bridge—something that users can occasionally insert when they wish to share experiences—isn’t that far-fetched.
