1.
How
do
you
think
these
events
or
such
technology
might
develop
in
the
future

Future
development:
Challenges:
The
AI
is
programmed
to
do
something
beneficial,
but
it
may
develop
a
destructive
method
for
achieving
its
goal.
Opportunities
it
may
take:
People
can
use
the
AI
to
do
most
of
the
daily
chores.
More
and
more
people
can
be
free
to
do
work
of
creating
new
things.
Future
development:
Challenges:
Opportunities
it
may
take:
More
nanobots
will
be
created
to
help
doctors
to
find
out
the
root
of
a
disease
and
make
operations
more
accurately.
New
kinds
of
virus
may
appear
and
even
nanobots
can’t
find
out
where
they
come
from.
The
nanobots
may
bring
more
people’s
life
back.
Future
development:
Challenges:
Opportunities
it
may
take:
Work
in
factories
will
be
more
efficient.
More
labor
force
can
be
freed
from
working.
More
and
more
workers
will
be
out
of
work.
People
will
learn
more
about
how
to
create
a
machine
and
how
to
operate
it
to
help
work.
Future
development:
Challenges:
Opportunities
it
may
take:
More
animals
even
human
beings
will
be
cloned.
Cloning
may
result
in
disorder
on
the
earth.
More
lives
will
be
saved
and
more
diseases
can
be
cured.
Future
development:
Challenges:
Opportunities
it
may
takes:
Air
pollution
will
be
decreasing.
There
will
be
glaciers
again
in
the
Arctic
Ocean.
There
may
be
other
threats
to
the
Polar
bears.
People
can
live
in
harmony
with
the
Polar
bears.
Listen
for
predictions
When
listening
for
predictions,
you
should
listen
for
the
use
of
the
future

in
particular
the
future
