Dude's Dad was a property tycoon. Quoting wikipedia: Arrillaga established his career as a real estate developer starting in the 1960s, partnering with Richard Peery in acquiring California farmland which they converted into office space. Their partnership took off with the growth of the semiconductor industry and other high-tech businesses, such as Intel,[2] in what became known as Silicon Valley.[6] Arrillaga and Peery converted thousands of acres of farmland into office space in cities such as Mountain View, San Jose, and Sunnyvale to meet the industry's needs.[2] Over a period of 50 years, their partnership, Peery Arrillaga, built over 20 million square feet of commercial real estate, becoming one of Silicon Valley's biggest commercial landlords.[9][5][8] In 2006, he sold over five million square feet of his real estate holdings for roughly $1.1 billion to the real estate division of Deutsche Bank.[6][2] In 2020 Arrillaga ranked No. 339 on the Forbes 400 list of the richest people in America.[6] In October 2020, his net worth was $2.5 billion.[6]
