In 1888, the London-based accounting firm that became PricewaterhouseCoopers (PwC) faced a major technological upheaval thanks to the Burroughs adding machine. The first-ever mechanized calculator, an invention by William Seward Burroughs, cut the time to perform accounting tasks in half, and PwC's hundreds of workers had to quickly master the new system, or get left in the dust. Today, PwC isn't simply an accounting firm--now it's a global consultancy with 250,930 employees in 158 countries, raking in $43.1 billion in revenue in 2018--but once again it, along with thousands of other companies, faces a seismic technological shakeup with the advent of AI and other advanced technologies. It's rising to meet the challenge by preparing its workers to use digital technologies at all levels, from entry-level staff to C-suite executives. And it's not alone in its reskilling push--AT&T, IBM, Walmart and other forward-leaning companies also have major retraining programs underway.
