Incredible complicated
Many years ago there were briefing offices at GA aerodromes where one could drop in or telephone and ask such things as "I want to fly from A to B - what's the best way to plan through Willie airspace and what level?" and you'd be given the good advice or they'd find out. And ask a myriad of other questions and seek advice, talk to the met guy even. Or people were sufficiently trained and skilled to figure it out themselves.
Then as a cost cutting measure someone closed all the briefing offices down, and those in the consolidated briefing offices didn't have local knowledge and over time became deskilled and pilots were encouraged to self help rather than wait for lengthy period in telephone queues.
Consequently pilots were left to either try to figure things out themselves or perhaps ask an instructor, who in time also themselves became deskilled and less knowledgeable.
And that's pretty much where we are today.
