@lightweight That isn't a great comparison, as teaching someone to drive a petrol car is a generic skill that will allow them to drive a diesel or electric or any other car and that skill can also be applied to the driving of most vehicles with a few modifications.

That alone doesn't implicitly doesn't denigrate public transport, considering that public transport is sadly not suitable for many tasks, one example would be transporting many objects or large ones like fridges or mattresses.

Teaching microsoft and apple products is rather like teaching someone to drive two different coal-fired billycarts (one is covered by window glass, the other covered by shiny glass), with controls like pic related https://en.wikipedia.org/wiki/File:Backhead_and_cab_of_former_South_Australian_Railways_T_class_locomotive_no_186,_19_May_2018_(DBinion).jpg - the skills are only applicable to other kinds of vehicles at a very rudimentary level.
