I do know from experience that networks are complicated and users are dumb, but I still think that if someone with barely any knowledge and without malicious intent can mess with your network then something’s wrong with the setup.

But if the bio or art major can seriously affect your network then is that even their fault? What if someone had skill and malicious intent?

If someone deploys their router using a uni network as wan then I don’t see how that could affect other uni network users? I can imagine some internal services might not work behind such a router but it would be illogical of the user to blame anyone but themselves.

Can you give some examples of issues you mention?

The movies usually show an asystole being defibrillated and that is not done. To the best of my very limited medical knowledge you first need to use CPR and medication to get some electric activity from the heart to defibrillate.

I understand and agree with your attitude to buying a car on credit. Two semi-objective justifications I can see are safety and quality-of-life.

Newer and better cars are safer, and you might not have even a minor collision throughout the whole lifetime of the car, but the (hopefully never) day a crash happens you’ll be forever grateful to yourself you bought this car. And if you have some “smart” assistants on-board those actually can make you not end up in the accident.

From my experience I have realized that (within reasonable bounds) if spending more on something results in substantiality higher quality-of-life then it’s a money well spent. Because you end up being happier, calmer and actually more productive if you don’t have to waste your energy on inconvenient things.

Not sure if that makes you feel any better…

Sorry mate, those figures with no meaningful captions are borderline incomprehensible. Like, what’s the difference between first and second figure?
