> Though sadly it will be a while until we will hear: "You are visiting Hacker News, in a simple look and without any images, it features a list of links to articles and a menu at the top. Do you want me to read the articles titles, continue with accessing the menu or a more detailed description of the page?"
Sadly? I strongly disagree. If all my human-computer interaction would be like communicating with Siri/Google Now (e.g. conversational), I would have ditched computers years ago. It's all about giving semantic information to screenreaders so the user can eficiently navigate that content. In the rare case that I need some kind of human description, I just share my screen with someone that has working eyeballs.
FYI, I'm totally blind.
