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.
Well actually I would love html to be more to be like latex/markdown, I just thought, that if I recognize it as a list, it should be parsed by a screen reader as such too.
May I ask you which screen reader you use and at what speeds? (or do you use some braille screen?)
If you expect to accomplish that via a community effort to make tools for deaf people, you're likely right. But i bet we aren't that far away from "Hey alexa/siri/google, what are the top stories on hacker news right now?"
