Well,
the
new
Renaissance,
that's
a
pretty
optimistic
view
of,
you
know,
AI
systems
that
amplify
human
intelligence
is
under
control,
can
solve
a
lot
of
complex
problems,
can
accelerate
the
progress
of
science
and
medicine,
can
educate
our
children,
Yann LeCun (Chief AI Scientist)
00:19.100
You
know,
help
us
you
know,
process
all
the
information
of
bring
us
all
the
knowledge
and
information
that
we
need
to
to
see.
In
fact,
people
have
been
interacting
with
AI
systems
for
much
longer
than
they
realized.
Yann LeCun (Chief AI Scientist)
00:37.060
Of
course,
there
is
LLM's
and
chatbots
now
for
the
last
three
years.
But
before
that,
you
know,
most
like
every
car
sold
in
in
in
the
EU
and
most
cars
sold
in
in
the
US
have
what's
called
ADAS
advanced
driving
assistance
systems
or
automatic
emergency
Yann LeCun (Chief AI Scientist)
00:59.180
braking
systems.
you
know,
a
camera
that
looks
at
the
window
and
stops
your
car
if
you're
about
to
hit
a
pedestrian
or
another
car.
Um,
it
saves
lives.
Um,
you
you
get
an
X-ray
today,
let's
say,
a
mammogram
or
something.
You
know,
at
the
bottom
it
says
the
thing
has
been
Yann LeCun (Chief AI Scientist)
01:15.600
reviewed
by
an
AI
system.
It
Yann LeCun (Chief AI Scientist)
01:18.000
saves
lives.
Um,
you
can
get
an
MRI
now,
full
body
MRI
in
40
minutes.
Um,
this
is
because
you
can
accelerate
the
process
of
collecting
the
data
because
AI
systems
can
uh
can
sort
of
fill
in
the
blood
You
don't
need
to
collect
that
as
much
data
for
this.
Yann LeCun (Chief AI Scientist)
01:34.000
But
also
all
the
news
you're
seeing,
whether
you
connect
on
Google
or,
you
know,
Facebook,
Instagram,
any
social
network
is
determined
by
an
AI
system
that
basically
caters
to
your
uh
interest.
Um
and
so,
you
know,
AI
has
been
with
us
for
for
a
while
already.
Janna Levin (Professor of Physics and Astronomy)
01:52.560
But
you're
saying
we
should
be
impressed
when
they
can
pour
a
glass
of
water
and
Yann LeCun (Chief AI Scientist)
01:56.240
do
our
dishes.
Pour
a
glass
of
water,
do
our
dishes,
you
know,
uh
driver
cars,
like
learn
to
drive
our
cars
in
10
hours
without
the
cheating
practice
without
all
the
the
cheating
with
with
sensors
and
mapping
and
and
and
hard
coding
of
rules.
So,
Yann LeCun (Chief AI Scientist)
02:12.480
um
yeah,
this
is
going
to
take
a
while.
Um,
but
this
is
going
to
be
the
next
revolution
of
AI.
So,
this
is
what
I'm
working
on,
okay?
Um,
and
the
the
message
I'm
being,
you
know,
carrying
for
a
while
now
is
um
is
okay.
LLMs
are
great,
they're
useful,
we
should
invest
in
them.
A
Yann LeCun (Chief AI Scientist)
02:32.000
lot
of
people
are
going
to
use
them.
Yann LeCun (Chief AI Scientist)
02:33.440
They
are
not
a
path
to
human
level
intelligence.
They're
just
not.
Right
now
they're
sucking
the
air
out
of
the
room
anywhere
they
go.
And
so
there's
basically
no
resource
left
for
anything
else.
And
Yann LeCun (Chief AI Scientist)
02:48.040
so
for
the
next
revolution
we
need
to
kind
of
you
know
take
a
step
back
and
figure
out
what's
missing
from
current
approaches.
And
then
I've
been
making
proposals
on
this
and
working
inside
of
Meta
for
a
number
of
years
on
this
alternative
approach.
It's
Yann LeCun (Chief AI Scientist)
03:09.280
come
to
the
point
where
you
know
we
need
to
kind
of
accelerate
this
this
progress
now
because
we
know
it
works.
We
have
early
results
and
so
that's
the
plan.
Janna Levin (Professor of Physics and Astronomy)
03:21.480
Okay,
I
could
we
could
have
a
whole
another
hour
starting
right
here,
but
I
hope
you'll
all
join
me
in
thanking
our
guests
for
an
incredible
conversation.
Thank
you
so
much.
