Except gen Z didn't grow up with just an iPad, at least not the majority. A good amount of people had (or have) access to a laptop or family computer. Thats why I say that the gap has just gotten wider. Some people, eg. the ones that just had an iPad and all they ever did was social media and mobile games - sure, they know very little about computers. But the ones that did use computers (and thats not a small amount) do really know how to use it - which is not limited to the more or less office-focused skills of older generations.
