One of these two people will be a better operator of the car in unexpected situations, and can explain driving a lot better to their children, friends and others.
The problem I most often see in this kind of discussion, is more analogous to people discussing car behaviour on slick ice, when a long-haul trucker having a 40-year career in the Australian outback ridicules the entire discussion as fantasy because they certainly never had to deal with ice on asphalt, so it is impossible for it to occur to anyone else.
This is extremely common with those who have a long history in Windows use and no other OS experience, and with those who expect the vendor to provide a solution path for every conceivable problem. In particular, they will ridicule the
Unix philosophy, and ignore any arguments showing how it is still the most effective paradigm in e.g. high-performance computing, because it just doesn't fit their personal experience. They will demand frameworks and cathedrals instead of modular libraries, because they find the responsibilities associated with freedom scary or difficult. Similarly, they often make claims about various software licenses and international intellectual property law, based on something they
believe (having perhaps heard it thirdhand at a coffee shop before), and if their opinion is shown to be bullshit, start spouting how only lawyers should be allowed to discuss this stuff online. Qt licensing is a particular sore spot.
In short, it is better to just ignore the rants. It's not like they're going to respond rationally anyway.
