Billionaire tech investor Peter Thiel is set to deliver a four-part lecture series on the theme of the Antichrist at the Commonwealth Club in San Francisco, beginning 15 September. The program, scheduled to run over several sessions, marks an unusual public foray by the PayPal co-founder and Palantir Technologies chair into theological discourse. The Commonwealth Club, a longstanding forum for civic debate, has not yet released ticketing details or the full schedule but confirmed the engagement will span four installments. Thiel, known for his interest in transhumanism and longevity research, has previously used public lectures to articulate contrarian views on technology, politics and philosophy.
