wrong on two counts
I have no reason to question the author's knowledge on the history of computing (I didn't study the article too closely) but he makes two fundamental misjudgements about the nature of people.
Firstly, many (and an increasing number of) computer attacks do/will not arise from a lack of hardware/operating system protection; they come from things like social engineering attacks - fooling the naive user into doing something they don't understand.
Secondly, we are now in 2014 yet still a large proportion of the worlds population does not have access to drinking water, and any relatively rich nation spends a large proportion of its wealth on going to war (and inventing machines to kill people). Over half the world's population still believes in God for f***s sake. Humanity is simply not rational nor capable of acting in the best interests of the whole world.
