So I started my first job
as a computer programmer

in my very first year of college,

basically as a teenager.

Soon after I started working,

writing software in a company,

a manager who worked at the company
came down to where I was,

and he whispered to me,

"Can he tell if I'm lying?"

There was nobody else in the room.

"Can who tell if you're lying,
and why are we whispering?"

The manager pointed
at the computer in the room.

"Can he tell if I'm lying?"

Well, that manager was having
an affair with the receptionist,

and I was still a teenager,

so I whisper-shouted back to him,

"Yes, the computer can tell
if you're lying."

(Laughter)

Well, I laughed, but actually
the laugh's on me.

Nowadays, there are computational systems
that can suss out emotional states,

and even lying,

from processing human faces.

Advertisers and even governments
are very interested.
