I wonder how often it will happen again going forward now that we are in the age of "helicopter parenting" where parents over-supervise every activity their children are engaged in. Kids today can't even go to Little League practice without their hovering parents sitting out there in lawn chairs cheering every time they properly field a ground ball. Then after practice, it's right into a mini-van for the obligatory trip to a ice cream stand where the parent carefully selects a treat that conforms to some specific caloric value that the parent deems appropriate.
Steve Wozniak and Steve Jobs were basically left to their own devices and did not get a lot of parental interference as they tinkered away and began to build their business.
If they tried they’d be crushed by patent threats from the established companies.
