Como virar operador de prompt de AI?

I watched Lain some weeks ago for the first time and it was quite shit. Basically proto millenial meta except nothing made sense at all. It's like if you tell a tech illiterate what videogames and internet are in 98-99 and he makes an anime. The only good things were the mood and style.
>Nothing is explained
>More questions by each episodes
>Only the internet is futuristic, everything else is 90s
So the whole planet is wired. How? Those guys with the laser pointer googles. What were the laser pointers for? If the ""god"" liked Lain why does his followers wanted to kill her? If being on wired is such a good thing why didn't it spread faster? Why did Lain remove herself at the end? What was the point of that?
