Conscious robots working in our homes by 2030, experts say
By Dick Pelletier
Ever since Bradley the family robot
received his level-4 upgrade, he has been difficult to get along
with. Bradley now has a conscience, and although he is still
eager to care for Grandmamma, keep the house spotless, maintain
security, and run errands; he wants more “alone time”, and he
recently joined a robots rights group. We wonder what’s next;
vacations; sick leave; going on dates?
Although this scenario may sound
like fiction, it could depict a real situation in the future
when robots, programmed with human consciousness, will want to
be treated like us.
Tomorrow’s robots could easily
maintain our homes, care for our aging population; even become
our soldiers of the future. But here’s the concern; robots may
be required to make decisions that could affect our lives, and
we will place more trust in a robot that expresses human
consciousness than one that simply acts like a machine.
But before robots can become
conscious, researchers must identify what consciousness is and
where it is. NY Times science writer David Dobbs believes
that during the next decade, scientists will discover the neural
networks that generate this elusive human trait. We may then
find answers to some of the most profound questions in science:
can the brain understand itself, and what is “self”?
“Once science unravels
consciousness,” Dobbs says, “researchers could then create what
might be called a ‘consciometer’ – a set of tests (probably an
advanced version of a brain scan or EEG) that can precisely
detect and measure consciousness.”
The ability to identify
consciousness will change how we make end-of-life decisions,
like the Terri Schiavo case, and beginning-of-life choices
involving abortion. In both instances, religious conservatives
may not be happy with the results.
After we understand
consciousness, we will know the brain’s capacities and limits
for thought, emotions, reasoning, love and all aspects of human
life, say experts. Scientists are now studying how groups of
neurons form functional networks when we learn, remember, see,
hear, move, and love. And how these give rise to altruism,
sadness, empathy and anger.
When the discussion turns to
these imponderables, neuroscientist Gerald Edelman dives right
in. Nobel Laureate, physician and cell biologist, Edelman is now
obsessed with the enigma of consciousness – except he doesn’t
see it as a mystery. In his grand theory of mind, consciousness
is merely a biological phenomenon that one day can be built into
machines.
In a recent Discover Magazine
interview, Edelman talked about his research into synthetic
consciousness and construction of a brain-based device (BBD)
that he believes will one day become a superintelligent machine.
Although his BBDs resemble R2D2, he says they are not robots,
“because they do not use artificial intelligence; they operate
similar to mammalian brains.”
Edelman’s team is now working on
a new BBD called Darwin 12. It has legs and wheels with 100
different sensors enabling it to climb stairs and navigate
unknown circumstances. This, they hope, will bring them closer
to creating a truly intelligent machine.
Clearly, developing conscious
robots poses unknown, possibly even dangerous consequences; but
futurist Ray Kurzweil and other experts predict that by as early
as 2030, we will experience this “magical future.”
