Yes it's my favorite book.
Mike was a billionaire, the nest had a literal pot of money that anyone could just take and do whatever.
But no he would love Elon. To grok is to understand fully, to understand is to know, to know is to love. Essentially everyone has a redeemable quality and Mike would love that part especially but also all the lesser parts and even the hard to love parts because all those other parts are part of what makes the part he truly loves.
