The Three Laws are the only way in which rational human beings can deal with robots - or anything else. But when I say that, I always remember (sadly) that human beings are not always rational!
Human intelligence
Seeing
Uses about 30% of our brain
Optic nerves contain 1 million fibres
Hearing
Uses about 3% of our brain
Auditory nerves contain 30,000 fibres
Speaking
Uses about 50% of our brain
Thinking
Uses most of our brain
Seeing
The process of analysing and understanding images
Hearing
The process of identifying speech and translating it into text
Speaking
The process of translating text into synthetic speech
Thinking
The process of identifying, analysing, understanding, and responding to data
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm
1976: Simulating sight in real-time
Estimated 1,000 MIPs
Cray 1 (fastest computer) capable of 80 - 130 MIPs
2011: Computer vision applications
Averaged between 10,000 and 1 million MIPs
1980s: Moravec's paradox
High-level reasoning requires little computation, but low-level sensory processing requires enormous computational resources
A chair
And another
And one more
2006: Cloud computing
2016: Facebook image recognition
One person in a room close up
2017: Microsoft SeeingAI
2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law
1993: Apple voice recognition
2016: Google's Deep Mind translation
2013: Kinetic Sign Language translation
1961: Daisy Bell
2014: Amazon Echo
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law
