Once you go 60FPS you'll never go back.
Learn what? People play the games and feel something's wrong, you can't bend the physics, only try to deny them, but it won't have any actual effect. And no, motion blur also doesn't fix anything. It's been talked to death already during PS360 gen how shitty most of the games control, and at the same time CoD was universally praised for it's controls, how it plays. RAGE while not being a huge commercial success was also praised for it's controls, because Carmack put all the effort so the game would run at 60Hz. Many people (like myself) left the console market and moved entirely to PC once they read that PS4/XB1 games yet again run at garbage 30FPS. What people get used to is pretty visuals, the WOW effect fades away really, really quickly, after minutes literally, and then you're left with something that's not enjoyable to play at all, exhausting even.
What's annoying is at this day and age people still defend 30FPS. But the reasons are rather obvious tho, people can't fight their console wars on the internet without pretty screenshots, they need that ammo. And the best part is that those who desperately defend 30FPS can't decide what they really want either - 4K is a waste, RT is a gimmick, but at the same time 1080p is last-gen and unacceptable, where no longer than a year ago many claimed that 1080p, just like 30FPS, is also enough and we don't need more, and it's better to put the resources into better visuals. But again - people play games, not watch them, let alone static screenshots on internet, in motion, a.k.a. when actually playing the games, the image and motion clarity are what matters the most, at least for most people.
But luckily, I'm pretty sure Sony and MS are tracking the data, how many people use the performance modes and how many the fidelity ones, and seeing people's overall feedback it's safe to say that 60FPS is (finally!) here to stay, especially when all it takes is just lowering the resolution a bit.
