First of all thanks for enrolling as fan. This is the first time I had one
in my entire life.
Web 3.0 is meant to be an integration of all the computers connected to the world wide web and covert them in one unique global machine where Internet will be the OS. As Kevin Kelly in the video I linked in the blog, this machine should never fail and sumes less than 5% of the electricity produced in the world.
I'm not a specialist in this but just a current person amazed by the possibilities technology has and eager to know how is this going to help ALL of us improve our way of living in the near future.
I hope I managed to answer your question. I can only refer to Kevin Kelly and WIRED magazine should you need further information.
