It might not be that different from using a social network like Lemmy, you wouldn't necessarily have to be assimilated (in the sense of losing your identity), but you could more easily put yourself in someone else's shoes, your experience would be augmented. In an ideal world this technology could give you access to my memories and give me access to yours, I would know everything about you and you would know everything about me (no privacy, yes, but no power imbalance either), lying would be pointless and we would be able to feel what each other feels in the way we feel.

A good part of Humanity's problems are problems with language, communication, understanding others or rather the lack thereof. A technology like this could literally put us in other people's heads and thus perhaps help us develop greater understanding and empathy, at least I have hope for this.

That said, I don't trust the people running these companies to develop this with the benign long-term goal I've described. 🤣
