I've found this to be very common among all generations, particularly boomers/greatest generation. Everyone has ingrained beliefs and nobody likes when those are contradicted, particularly in public and with factual points that can be hard to rebuff, at least on the spot.
There are so many things I have to be careful not to say to my parents and older relatives lest they burst a blood vessel, as well as my senior neighbors and coworkers. My peers, however, are used to hearing all sorts of things and are usually happy to discuss or debate any topic without taking things personally or as an insult to their heritage or tradition.
I think that there are always going to be generational differences, and that it isn't helpful to blame generations. Instead, we should all work to identify and solve issues rather than point to the "others" and say they are at fault.

Virtualization hypervisors typically emulate hardware. They provide a "virtual machine." It may not be real hardware, but for most purposes the function and appearance is the same from within.
I think you and the author may be in agreement on this topic.
Following your example of cars, having a large gas-guzzling full-size truck when you drive by yourself 5 miles to the supermarket once a week would indicate that the vehicle is being used at a low percentage of its capacity. If it were loaded up hauling heavy equipment and materials, to and from jobsites for example, then it would be near 100% capacity.
For the weekly grocery run, it is wasteful to have this truck since it is used at low capacity. One would be better served with a much smaller vehicle, even perhaps one that is human-powered (such as a bicycle).
"Ideally, the resource gets used at 100% of its capacity: we have enough capacity to serve our needs without generating queues, but not so much that we’re wasting money on idle resources."
The large (expensive) truck only used on the grocery run would be wasting money on idle resources, since it is capable of doing much more work but is rarely used.
Car decays by age but mainly by miles. Sooner or later the car will have reached 100% capacity even if just used once a week. Which I think is a good point against the "efficency" idiom.
