All right. I'm pretty sure you agree
artificial intelligence
is super exciting.
In fact, it's maybe the
most exciting thing to
happen to humans for a
very long time, maybe ever.
There are these people
called digital utopians
and they think that AI is
going to be so awesome.
It's going to make our lives
so much better with all these
hacks and machines and little
tricks that it can do for us.
Also, there's a bunch of very,
very smart people who are saying
that artificial intelligence
could actually be really scary.
Let's look into that a little bit.
Now, in the short term,
I think what we're going to see
from artificial intelligence
is a lot of jobs changing.
Think of drivers, taxi drivers,
bus drivers, postal workers,
when self driving cars come
along where human no longer
drives the car, so it's artificial
intelligence now, there's
a lot of those drivers who
are going to lose their jobs.
In fact, the Foundation
for Young Australians,
they expect that
half of the jobs that
you're currently thinking
about moving into
Accounting jobs, medical
jobs, all sorts of jobs.
This is just the short term though.
If the world can create
a general intelligence,
artificial general intelligence,
we talked about this
before, the ability for
machine to learn and get
smarter and be really,
really good at a lot of
different things.
This would be interesting
for the world because
if this thing gets
smarter, and smarter,
and smarter,
then it becomes smarter than us.
This can be a really scary
idea, but let me
explain it to you in a
really non-scary way.
Now, there's an AI that
was built called DeepMind.
This is a non human machine that's
job is to learn as fast as possible.
Now, they put this AI
into a computer game
and they said,
"Your job is to get
as many points as you can,
that's it."
They didn't tell it other ways
that it could win the game.
You'll see as the
machine starts playing
the game,
in the first 10 minutes or so,
it makes a whole
bunch of errors
just like we would if
we were learning a game.
Then over the next hour or two,
it starts to get really, really good.
In fact, it's playing better than
perhaps most of us could play.
It's learning as it's going.
Here's where it gets interesting.
At the three or four hour mark,
it's so good at the game, it's
learnt so much, that actually
it's the best player in the world.
It is better than any human
that's ever played that game.
It is an artificial intelligence, 
it's a non-human machine
that is achieving 
a complex goal.
You might think, "Oh, that's cute.
You know this machine, 
this artificial intelligence,
can win the computer game,"
but actually what's most
interesting is that
it's learned how to
win the computer game.
Imagine if you let this
thing learn other things.
Imagine if it started learning
every language the world's ever created,
and that takes it four or 
five hours to do that.
You accidentally leave
it on while you're
making coffee and you come back
and you realize, "Wow,
this has just memorized
every article on Wikipedia that's
ever been written before." 
That's exciting
for the world,
this machine can learn a lot,
but if it's getting smarter than us,
we need to actually 
be concerned.
For example,
we're smarter than tigers
even though they're this
massive, aggressive animals.
We're smarter than them, so we win.
If this artificial intelligence
becomes smarter than us...
does it win?
Isaac Asimov is a sci-fi writer and
he said that science is actually
gaining knowledge faster, perhaps
than society is gaining wisdom.
It's a really interesting concept.
Irwin Corey, a philosopher, he said,
"If we don't change direction soon,
we'll end up where we're going."
The world is on the brink right now
of potentially creating these 
general intelligences,
these incredible machines 
that can learn really, really,
really fast and get really smart.
That could be awesome or
it could be bad for us.
Before you think,
"Oh, oh,
the world's going to end,
here come the machines.
The killer robots are
taking over." There are some
really smart people
working on this right now.
Also, we need you working on it.
You are the next
generation of AI builders.
You are going to be
using AI technologies
to make a difference in the world.
That is what the AI for
Good challenge is all about.
So in this section,
we're going to engage
with the ethics,
with the decisions that have
to be made around
artificial intelligence,
and you are going to
be in the driving seat.
