Jim Clark and WebMD
Yes that Jim Clark. Serial billionaire.
His idea with WebMD was to drag medical care into the digital era. It did not.
Jim Clark stumbled once (if memory serves) trying to invent video streaming. Florida I believe. Too far ahead of its time.
If he was also 20 years too early with WebMD then maybe Bezos and Buffett are on to something. It is about time.
