The article explains that when War Games was released it created a flurry of news articles and reports on if it could actually happen. So much so that it forced Congress to impose legislative acts regarding the internet. NORAD even had to come out and make a statement informing the public that a system of checks and balances are in place that present a "War Games Scenario."
To a filmmaker, this is the highest praise, starting a discussion about the themes in your movie that actually effect real world issues. The fact that a simple movie about government hacking can cause such a riot shows the publics anxiety about this unknown internet at the time. The internet was fairly new, for the public at least, and we did not know about it's true power. War Games showed the tip of the iceberg of what hackers really can do.
The older general in the movie represented the older generation. He was not embracing of the computer's power and wanted everything to be done the old fashioned way, with human involvement making the decisions, which is how it is always done at NORAD. Lightman and the tech guy at NORAD represented the newer generation. The tech guy showed that computers can take care of human error, and to some extent they can but the internet was in such a premature state that it would be irresponsible to base a system around that. Lightman showed the power of the internet in the hands of the teenager who knows exactly what they wanted to do.
The internet was a huge social anxiety, and I think it still is. The article describes it as a "hacker mystique" and I think that that is a completely accurate term. The fact that hackers have access to bank accounts, plane tickets, school grades, and government database, they can control the world. And when you control all of those, you do not want to be their enemy. The situation in War Games may not be completely possible with how NORAD is set up but it is still probable. And even then, hackers can find many other ways to control the outcome of something.
Today we still have that hacker mystique about us. 4chan with the click of a mouse can take down massive credit card company sites or find the address of any single person in the world. Get on their bad side and you will be in a world of hurt. Because of this, pushes have been trying to be made to get rid of the so called net neutrality, the fact that every piece of information on the internet should be treated the same and therefore the users should not be charged or discriminated based on what content they access. This of course flies in the face of 4chan and they backers of this act have been put on blast, so to speak, on the internet. I'm not sure how much the public fears the internet today, seeing as how it is ingrained into almost every aspect of our lives. I think the people that back acts like SOPA and similar ones are just like the General and fear net neutrality or they are using it as levereage to grab a profit with internet providers.
I am a strong supporter of net neutrality and I think that all information should be free. I understand that many social anxieties come from this debate and that social anxieties have been around since the birth of the internet, and I think they will always be here.
