I think it’s very similar - humans used whatever tools they had to “enhance”. In past times, it was psychedelics, trance experiences, pain, rituals, fasting and similar things, and now we have other things at hand to “improve”. While in past times, many of those tools were used for spiritual things like connecting to the gods, ancestors, dream-lands or something like that, we now, with religion (fortunately) on its decline, use it to connect to some sort of hardly-definied “future” or “technology”. Still, the meaning for the individual might be very similar, lots of people in this forum feel that their implants are a very intimate, important part of themselves.
