On Monday, Microsoft founder Bill Gates said that most of his fortune will be spent on improving health and education services in Africa over the next 20 years.
The 69-year-old said that "by unleashing human potential through health and education, every country in Africa should be on a path to prosperity".
Speaking in Addis Ababa, Ethiopia, he also motivated Africa's rising innovators to think about how to build AI to improve healthcare on the continent.
Gates announced last month that he would give away 99% of his vast fortune by 2045, by when his foundation planned to end its operations.
"I recently made a commitment that my wealth will be given away over the next 20 years. The majority of that funding will be spent on helping you address challenges here in Africa," he said in an address at the African Union headquarters.
Gates said his foundation would focus on improving primary healthcare.
"What we've learned is that helping the mother be healthy and have great nutrition before she gets pregnant, while she is pregnant, delivers the strongest results," he described.
"Ensuring the child receives good nutrition in their first four years as well makes all the difference."
In a message to young innovators, the tech giant noted that mobile phones had revolutionised banking in Africa, therefore, AI should now be used for the continent's benefit.
He explained: "Africa largely skipped traditional banking and now you have a chance, as you build your next generation healthcare systems, to think about how AI is built into that."
