"It's about an old man who was cut off from computation [snip] and now has access to it... And this guy's dad being able to use a computer for the first time, after decades of being unable"
You have to read a lot into the post to come up with that interpretation.
We don't know why the father refused to interact with a computer before. There's no evidence in the blog post that he was "unable". That he decided to use an iPad doesn't mean that Steve Jobs gave him the miracle of computation.
If the father had been nearsighted but refused to wear glasses for many years, then saw his brother wearing a new style of frames and decided to finally get some himself, would we idolize the frame designer in this way?
