Tech guru and venture capitalist Kai-Fu Lee sticks to his 2017 prediction that artificial intelligence (AI) will replace at least half of the global human workforce by 2027. Lee, who has held executive roles at Apple, Microsoft, and Google, believes that AI will become a backbone technology, surpassing the importance of electricity and the internet combined. He sees repetitive jobs like truck driving, telemarketing, and assembly-line work as most vulnerable. Lee is currently the founder and chairman of Sinovation Ventures and 01.AI, both focused on developing global tech products and services.
