I think you're still at that point that you need to read for yourself about it. We cannot spoon-feed you all the info because it's not even humanly possible by simple dropping 14 years of information just like that.
I think there is nothing wrong with this type of question, it's not spoon-feeding at all because there are a lot of misleading information about Lighting Network and it's hard for a newbie to understand what's true and what's false, especially when search engines don't work the way they should.
That's exactly why I gave him some basic topics where he could start reading. And then, for sure he will find peripheral information that will complement that one and will give him a pretty good start!
