John McAfee is the founder of the McAfee security software company, one of the first and, to this day, one of the biggest. But it's what he has done since leaving the company in 1994 that has attracted him notoriety. After working on instant messaging software for a few years, McAfee devoted himself to thrill-seeking: yoga, jet skiing, and "aerotrekking," or flying small aircraft at low altitudes. After the 2008 financial crisis reportedly wiped out most of his personal fortune, once estimated at $100 million, McAfee decamped to Belize, where he began promoting a business venture aimed at halting the spread of bacterial resistance to antibiotics. But as science writer Jeff Wise (who also wrote the aerotrekking article) detailed after interviewing him in 2010, McAfee's commitment to the project seemed half-hearted at best, and his behavior came off as erratic and even paranoid. In a follow-up article, written after Belizean police raided McAfee's compound on suspicion of illegal weapons possession and drug manufacturing, Wise explores how "the enlightened Peter Pan seems to have refashioned himself into a kind of final-reel Scarface."
