There's a language to UIs that evolves over time. The menu hamburger, the on/off circle with a line. Take those back a decade or more and you would have the same problems, but eventually they percolate through people's experiences and expectations and you can rely on people knowing what they are now, for the most part (it helps that the on/off icon is used for physical devices too).
Pull down for search is something that it maybe Apple is trying to cement (and only for mobile, I guess?), but hasn't crossed (and maybe won't) to Android devices. Apple is known for doing stuff like this and pushing changes, sometimes it takes, sometimes it doesn't (e.g. no floppy in laptops, no CD-ROM in laptops, no Mic jack, etc)
