I think the key takeaway that led to the title is that last quote from him, paraphrased: At 94, you don't worry about losing your job. Presumably he's saying he's taking huge risks/being bold/not worrying about following other people's advice or conventional wisdom? He can do this (again, presumably) because he can live off his retirement funds/investments for what's left of his life. And he's already got major success behind him that can continue to define him, even if he hadn't come up with this new promising battery now.

So from the perspective of younger (than 94) people, is there anything we can do to emulate his experience? Take huge risks/be bold/don't follow conventional wisdom? It's risky, if you have anything to lose. It's seriously impressive when someone pulls it off, though, and those are the stories we pass on in the media and over coffee or beer.
