Bill Gates, Microsoft’s co-founder and one of the original “nerd billionaires,” has pledged to donate 99% of his wealth to Africa by 2045. Announced in Addis Ababa, this bold move comes as the US withdraws support by cutting aid and shutting down USAID, founded by JFK in 1961. Gates’ $77 billion Gates Foundation, already the world’s third-largest charitable foundation, sets a new standard in philanthropy. His gesture is also a silent call for fellow US billionaires to uphold American soft power.
