Accenture CEO Julie Sweet has done something most Fortune 500 leaders only talk about: she blew up a 50-year-old organizational structure, rewrote the operating model she herself installed, and tied every employee’s promotion to AI fluency—all while keeping 786,000 people on board. The philosophical question her transformation raises is one of philosophy’s oldest: if you replace every part of something, is it still the same thing?
The ancient Greek paradox goes like this: After Theseus sailed back to Athens, the Athenians preserved his ship as a monument. Over time, its wooden planks rotted and were replaced one by one — until eventually, no original piece remained. Plutarch recorded the result in the 1st century CE, noting that philosophers were already split: one camp held that the ship was still the same, and the other said it was not.
