John Gruber suggests that the common Linux desktop interfaces of Gnome and KDE fall into the uncanny valley – similar enough to Windows for you to expect similar behaviour, but different enough to be problematic:
By establishing a conceptual framework that mimicks Windows, they can never really be that much different than Windows, and if they’re not that much different, they can never be that much better.
A fair criticism. In my house, we refer to the uncanny valley as the “creepy canyon”, because we’re all about alliteration.
I think that when robots are made more life like they will be more about war and for perverted people rather than for education or anything useful or like what Mori’s hypothesis suggests.
