This a great question to ponder; however I find that 20 years from now is extremely difficult to forecast never mind 200.

In 20 years, I would parallel some of Kurzweil's sentiments of human merging with AI/technology at a cellular level.

200 years will/may have vastly new technology that we can't even fathom. AI/Human N.0 may create an increasingly complex being that is able to understand more layers of reality. For all we know, we may be arguing over 1% of reality.
