While we agree UD is an unachievable goal, we would argue that the goal itself is problematic and ultimately inadequate to the continuously evolving situation of not only the inclusion of more and more disabled/extraordinary/eccentric bodies into “normal” society but also the ever-shifting ableness of any body as it moves toward inevitable failure.
I also agree that that UD is not achievable. This will be a large cost for all businesses to make everything have a universal design. This also will not allow any room for error anywhere in the world. This unrealistic goal will create a uniformed design that will make society boring quite complicated to say the least.
