How golden was Tim Cook's Apple?

Tim Cook has stepped down as Apple CEO after 15 years, handing leadership to John Ternus. Under Cook's tenure since August 2011, Apple's stock rose from $13.35 to $316.61, representing a 2,272% gain. The company's market cap grew from $347 billion to $4.7 trillion, increasing by $32 million hourly. While Cook quadrupled annual revenue, his long-term legacy depends on Apple's AI strategy, which currently relies on external models and partnerships with companies like Google.
