TLDR: Steve Jobs and Tim Cook led Apple in different eras: Jobs focused on groundbreaking products (iMac, iPod, iPhone) that defined the tech industry, while Cook transformed Apple into a $3.7 trillion company by expanding services and hardware (Apple Watch, AirPods). Jobs' tenure saw a rise in market cap from $2.5 billion to $350 billion; Cook increased it by $3.1 trillion. Now, as Cook's leadership extends beyond Jobs', discussions on succession are intensifying.
