Recently I spent an hour staring at an unruly mop of teenage hair on my computer. The owner was an 18-year-old Canadian called Josh Richards. That name probably means nothing to you if, like me, you are a staid member of Generation X. But if you belong to Gen Z, born between the mid-1990s and about 2010, you might squeal in delight — as one of my daughters did.

The reason is that over the past two years Richards has become one of the most successful “influencers” on TikTok, the platform where people post short videos of themselves, often dancing or lip-syncing. He has garnered 1.3 billion likes for his videos and 21 million followers. Richards is often shirtless in his TikToks and frequently accompanied by a posse of fellow influencers, known as the “Sway House”, who have been living together in Los Angeles.

Then, last month, Richards and other in-fluencers announced they were leaving TikTok to join a similar platform called Triller, where Richards will be “chief strategy officer” with a large equity stake — never mind that he has just left high school (he tells me he has no plans to go to college at present).
