So, I'm from Guatemala.
This is a public service announcement,
that is where Guatemala is.
(Laughter)
Also, that is not where they keep the prisoners.
That is called Guantanamo.
(Laughter)
Not the same place.
So Guatemala's right below Mexico.
And for the Americans in the audience,
and let this sink in, because it really applies in most ways,
for the Americans in the audience,
you can think of it as Mexico's Mexico.
(Laughter)
Just like the US doesn't want illegal immigration from Mexico,
Mexico doesn't want illegal immigration from Guatemala.
It's a smaller country.
It's a poor country.
And well, what can I tell you,
it has much better Mexican food.
(Laughter)
Guatemala is a very poor country.
And a lot of people talk about education
as something that brings equality to different social classes.
But I always saw it as the opposite, as something that brings inequality.
Because what happens in practice
is that people who have a lot of money can buy themselves a really good education
and therefore continue having a lot of money.
Whereas people who don't have very much money
barely learn how to read and write
and therefore never make a lot of money.
And this is especially true in poor countries.
Now, I was fortunate that I received a rich person's education
even though I didn't grow up rich.
And it’s because I’m an only child.
And my mother, who was a single mother,
spent all of her resources on my education.
And this allowed me to come to college to the US
and eventually get a PhD in computer science.
Now because of all of this
about 10 years ago,
I decided I wanted to do something
that would give equal access to education to everyone.
Oh, by the way, this is what I want to talk to you about today,
giving equal access to education to everyone.
At the time, I was a professor of computer science
at Carnegie Mellon University,
and I decided to work on this with my PhD student, Severin.
The way my brain works,
all of education is just too general of a problem.
So I decided, let's start by teaching one thing.
And then I started thinking, OK, well, what should we teach first?
Should we teach math?
I mean, we both love math.
Me and my cofounder, we both love math.
And, you know, we didn't decide to do math.
Then we started thinking, well, maybe we should teach computer science.
But eventually, and this is maybe surprising to people in North America,
eventually, we decided that the best subject to start with
was teaching foreign languages.
And let me tell you why.
