You have highlighted so much of what is wrong with the travel and airline industry today (and others of course.) They 'train' youngsters on clicking and pointing and dropping down clickboxes without giving the slightest concept of what they are actually doing or why.
Having spent a large part of my career working on airline distribution, DCS, and inventory systems, I saw this daily and am vehemently opposed to it. It may be fine for the public to book and check in this way, but it is not appropriate for airline staff to do so, and these front end systems are truly a double edged sword. I have always encouraged my clients to go the full training route, and many do so.
I imagine that to some extent the automation of cockpit controls and fly-by-wire is analogous.
Training is expensive. Ignorance is far more expensive and can be catastrophic.
