I think the challenge is when it comes down to resource allocation between different business units in radically different industries. Like how does someone who is not Jeff Bezos go about deciding whether Amazon should use its free cashflow to make big bold bets such as acquiring LionsGate for Prime Video content, expanding Amazon fulfillment centers globally, acquiring Humana for a push into Amazon health insurance or buying a chip fab to make Graviton chips. Perhaps the fact that Andy Jassy actually comes more from a business background means he'll do well.
