"It is also my right to give my personal opinion when I say that it is managed like an IT sect, because I can not imagine a developer listening to 300 hours of podcasts, at the rate of 8 hours a day, he would go crazy, That's why I said to delete them because they have no utility."

David has never made any podcasts, some of the community have and he has been interviewed a few times. Why will you not listen?

He gave you a link to a few in case you wanted to listen to one or two to get the big picture, so you then know where to dive in to learn about internet 2.0 from actual developer focused documentation. The podcasts are NOT for devs.

Devs should already have a big picture understand and be going through documentation and code. You asked the most basic question possible (how can I learn about this thing?), so you got the broadest answer, 'go dig, here's all the links from big picture to RFCs and code'.

David works like 19 hour days, how would he have time to walk you through huge mounds of documentation? You need to decide what it is that you want to learn about, then start there. You don't need any help or guidance, none of the other App devs or core devs were given a single doc either, yet they are all working away. 20'ish core devs and another dozen or more App developers all managed to get their head around SAFE after a few weeks/months of reading and asking questions. Why not ask any of them how they started learning about it and where the best docs are for the things you want to learn about rather than asking the head of the project who is way too busy for that? https://forum.safedev.org/
