“Don turned out to be one of my favorite people to talk to about physics. Truly a unique mind with that Richard Feynman ability of taking very complicated ideas and explaining them simply, without losing any of the essential brilliant insights at the core of those ideas.”

“I love it when great CEOs and great leaders are also engineers at heart and never stop tinkering, never stop building, never stop being at the low level of figuring out how systems work... That is the beauty of the tinkerer mindset that Toby embodies.”
