According to an interesting article I read:
“Machines will achieve human-level artificial intelligence by 2029, a leading US inventor has predicted. Humanity is on the brink of advances that will see tiny robots implanted in people’s brains to make them more intelligent, said Ray Kurzweil.”
A great example of this cyborg future is the hearing aid already in use.
Also according to the article, these are the CHALLENGES FACING HUMANITY:
Make solar energy affordable
Provide energy from fusion
Develop carbon sequestration
Manage the nitrogen cycle
Provide access to clean water
Reverse engineer the brain
Prevent nuclear terror
Secure cyberspace
Enhance virtual reality
Improve urban infrastructure
Advance health informatics
Engineer better medicines
Advance personalised learning
Explore natural frontiers
I think they forgot a really important one: getting along with each other!
