Well...I think human will be more similar like how computers evolving...Previously we install encyclopedia or any other medias like movies, music or pictures in our PC, now everything is available on the internet.

For Human, is the same like we don't really memorize phone numbers anymore, or email address or something other details. Everything we rely on media storage or internet.. Soon, human wont have to know anything, we just need to know how to OBTAIN and PROCESS.

If the OBTAIN method is simple, as easy as plug into some cables, or connected through frequency like wifi into our brain, then Human will become a PURE PROCESSOR. You are right human will pursue knowledge witout any borders, but we don't really keep it in our brain.

I wont relate this to the pseodo-science such as astral projection, higher conciousness or mutual vibration, but more towards modern computer technology. As our brain is so similar with CPU, RAM and Hardisk, while neurons are just like current in a computer, I can see a possibility that human will connect to the next generation of the 'Internet' or Inter-Humanmind-Network'
