Maybe… but maybe it can also be compared to spiritual practices where people end up being “possessed” or losing their free will for a certain amount of time? The human body can be “hacked” as well, especially with the use of psychedelics and some superstition-based manipulation… I don’t know if there is that much of a difference.
Why should this revolutionize what it means to be alive? What hopes do you have about this? If we go into sci-fi, the instant transfer of knowledge or emotions might be something interesting, but this is merely a different tool to reach that - we can already transfer knowledge via speech or writing, and emotions, at least partly, via empathy. So maybe it’s just a tool that makes stuff easier, but I’m not sure if it really changes that much.
Singularity is a different thing, of course
