Bill Gates is not some great thinker. He was born on third base and in the right place at the right time, and then absolutely ruthless once Microsoft had power in the industry. As a thought leader he is extremely mediocre.
I would have done worse, but I am a bad businessman. Being good at business doesn't also make you a revolutionary thinker in technology, let alone the broader themes that are discussed here.
I would be interested in hearing his thoughts on philanthropy and how he's working to convince other billionaires to follow his lead.
