>> Can you think of any other domain where this is expected? > Mathematics? A keyboard? In mathematics there are different notations used in different domains; sometimes different notations in the same domain. There are multiple different keyboard styles and layouts. To me, it makes sense for people to use a keyboard they like and works best for their language. And, no, I don't expect everyone to speak or work in the same language. >> People have different needs. > Truth is, most people have the same needs. In your view, you can't say most. You only allow for one system. Or if they have different needs are they expected to have those needs unmet? > I don't buy it. Heated debates happen between idealists and realists. I'm an idealist, and I'm sure other idealists will agree with the vision. Realists are selfish and simply don't want to get out of their comfort zone to improve the world. There are heated debates between idealists of different flavors as well. You expect them to all to agree? Or are they selfish if they don't? You're obviously very fired up about this. I think this idea is very naïve, though I wish you the best of luck.
