Why is bethesda incapable of creating a story that actually makes the player think...

>Synths are literally clones of people, they even use them to replace other human beings, the game is fucking stupid with this and only wanted synths so they could have "muh slave metaphor, and also Blade Runner" because they are creatively bankrupt
this has bothered me from the start
the game implies that synths are slave labor, but you don't see any of it. It makes absolutely zero fucking sense. Why would the institute use emotional androids as slave labor? You would NEVER want your slave labor to be sentient and self aware. They could have just modified some Mr. Handys for fuck's sakes.
Fallout 4 has some of the weakest factions i have ever seen in a video game. They all have the STUPIDEST ideals. None of them are believable and it seems like bethesda didn't even try to make them believable.
>Minutemen: Let's, uh, just build stuff lol
>Brotherhood of Steel: Let's take technology from people
>The Institute: Let's, uh, just make synthetic copies of people and kill settlements for no reason lol
>The Railroad: Let's give everything human rights because muh feels

They are just ideas from a hat, everything in FO4 is like they made a total of one brainstorming session and nothing else
