Stephen Wolfram

This person is a living genius who makes his contribution as a researcher and a scientist in an unprecedented open sourced form using highly accessible media. There is a daily live stream, youtube channel, open source wolfram engine that can do a lot of what Mathematica can do.

I think he deserves to be an exemplar for prospective entrepreneurs and researchers if they can even get close to that.

Many people live different lives and excellence can be achieved in many different ways. He is definitely one of the exemplar that I aspire to learn from.
