You may not be mistaken as a famous tech billionaire, but you may be mistaken as a well-to-do tech worker or even a tech startup lottery winner. An example of this is in luxury retail stores, fancy/business clothing used to be such a strong signal of high status that retail workers there would often ignore you if you walked in wearing T-shirt & jeans because they'd think you couldn't afford it. Nowadays, that's a lot less likely, they know too many people dress like this for a retail worker to safely assume anything. There are a lot of wealthy people who aren't in the news all the time and a lot of them don't dress like a traditionally wealthy person.
