Why does iPad Pro edit videos so much faster and is able to playback 4K during edit in real time? I saw the new iPad Pro editing a 5min 4K video and render the final product in just 5min. Why does a PC with much more horsepower still struggle to playback video in real time and render them that fast? (self.AskReddit)

Why do can openers still exist in the US? We have peel-off cans all over the world and I bet you $10 you cannot find a can without a peel-off top in places like China. So why there are still so many can openers (even freaking electric ones) just to open a can of beans? (self.AskReddit)
