Anything time-based. Fuck voicemail, I don’t have time to listen to the slow voice read everything out, give me a ui and words and let me read at 700wpm. Even shit like power buttons make me mad. I’m always doing stuff, I can’t dedicate 2 seconds to turning on my headphones because I’m using that hand for something else, like carrying food or opening something. The only bottleneck for how fast I can do something should be me. Bring back switches!
