Most pop songs look like they do in PT because it can. There are a couple of things you don't want to see getting made - legislation, sausage and pop music. Everything is beat matched - nothing can be off the grid. Nothing not the slightest untuned, no accidents (and we aren't talking about notes). A lot of the tools that exist were to fix mistakes. Now it is used to fix what is right. So what is integral to EDM and DM is now mainstream and squeezes the life out of rock and even pop, cause life is slop. Or at least rock and roll was. It was about emotion much more than precision.
Of course, major productions used to have great players. I think the Wrecking Crew movie is out - everyone should see it. Them boys can play. And they also added that indefinable something that is what music is about. The walking bass line from "These boots are made for walking" was something Carol Kane, the bassist, came up with on the spot. And basically defined the song and walking bass lines forever more. Now even I can sound as tight as Ms. Kane, but it doesn't mean PT will come up with the intro to the song on its own. But if that walking bass got played in the break, it is easy as pie to copy and paste a walking bass line for the intro. Maybe fix a few notes up so it doesn't sound exactly the same or put it in a better key going in. But it won't provide the genius to do it. And for that you have to cut it into a phrase or bar.
