I think that nature solves everything. We just need to be careful with our enery and oil. If we do that right, nature does the rest. The humanoid will never die, untill everyone is finished here, then we go to heaven.
Later we control technology by speech and thoughts. Maybe, we don't need to work with a computer, because the computer just thinks.
I certainly do not hope that the world will be mechanized, oh no. I think it look just like now, but on the inside it's more technical, like 'invisible' technology, or at least very small.
Technology isn't going to change our whole life, but maybe your communication with people and the 'ease of life'. If the technology is going to 'think', we have more time in our lazy chairs, or go to the the sport-school. (I preffer the first one!)
That's what I think. :-)
Tell whay you think too!
