My guest today is probably the world's most famous college dropout.
Of course, there have been other monikers over the years.
Computing pioneer, richest man in the world, global philanthropist, even tech supervillain.
Whatever your take on Bill Gates,
after years at the corporate coalface building a software empire and a vast fortune,
his priority now is giving that away.
And his ethos for doing it has been shaped by his international experiences and by science.
Famed for co founding the software company Microsoft, for the past 25 years,
Bill's attention has been focused on philanthropic efforts via the Gates foundation,
one of the largest charities in the world.
There, Bill and his billions have taken on issues around health,
inequality, education and climate change in some of the world's poorest countries.
And their impact has been undeniable.
From helping eradicate wild polio virus in Africa to supporting efforts which
over the past 25 years have more than halved global child mortality rates.
Bill says none of this work is easily accomplished, but most goals worth achieving aren't.
And as I suspect we'll hear over the next half hour,
he's not a man to opt for the easy route when there's a tougher challenge to take on.
Bill Gates, welcome to Life Scientific.
Thank you.
