and pay for electricity the way you used to pay for dirty kerosene, except that you paid it through your phone every day, 50 cents, and if you didn't make your monthly payments by the end of the month, the solar company could call you and maybe offer you grace or shut down your unit.

That was game on, solar energy revolution, because of the railways,

of M-Pesa, and as Sotoyo said, our 40 companies have now brought electricity to 300 million people.

It wouldn't have happened without this pay-as-you-go mobile payment system.

You've also ...

Agriculture is also historically a cash-based industry where there's been a lot of what they call leakage, petty corruption.

And you've also significantly reduced that.

And through our agricultural investing, we've seen just massive changes.

So thank you for that work as well.

In the interest of time, because Sitoyo and I share a mentor and someone we have all been imprinted by, one of the great moral leaders of our time, a man named Bob Collymore who ran Safaricom.

And in this time where we keep looking around to say where are our leaders, Bob stands as a giant that we lost to him tragically far too young a few years ago.

Sitoyo...

You're an African.

You have built one of the most important companies in the world.

You see a continent that is going to comprise one in four of us with a median age of 19.

How do you think about AI, the future, Africa's contribution in the context of the kind of moral leadership that Bob

demonstrate it for us?

I think that's a great note to end on.

Also, that corporate CEOs like Bob, like you, my friend, Sitoyo, have a role to play in the world today to stand up for those who are overlooked, underestimated, and who we desperately need to be realizing their human potential.

It is such an honor to know you, to work with you.
