While such information may certainly be educational to the folks in back, in the cockpit we have a bit more to do than be tour guides. Our job is to get you as the passenger, or your cargo and luggage, and often both, from A to B safely. This involves considerable complexity, not the least of which involves looking for other traffic, navigating, communicating, and handling a variety of tasks involving hundreds of controlsl and indications in the cockpit. Simultaneously.
Where some time allows, some crews are more than happy to provide a little information. Personally, when I'm traveling somewhere as a passenger, I find such announcements a nuisance. They interrupt music or a movie, they are barely audible and difficult to discern, and seldom can I hear what is said, let alone understand it.
If one wishes to learn geography, an atlas can be had for a very small price.
