As evidence, the author mentions the late average age that the underprivileged "received" their first computer. As I recall, one Bill Gates began hacking at an early age, not because his privileged family showered him with cutting-edge technology, but because he bent a few rules to gain better access to a terminal through school.
Let's not confuse resourcefulness with privilege.
iirc, gates went to a pretty well-off private school that actually HAD computers. i doubt that most people attending public schools in the 60's could even find a computer anywhere nearby. this is documented in Gladwell's Outliers (ducks!)
Note that I do not accuse the original author of trying to stretch this, nor you; just pointing out that if we're going back that far it becomes a completely different issue. (We can wish really hard that every child of the 1960s had access to computers for learning, but we might as well wish that every child of the 1860s had such access for all the practicality that has.)
