In a way, "practicality" is the place you arrive at only after considering more extreme, principled points of view. So if his role is to present one philosophical approach to technology, and you decide it's too extreme, at least it was there to make wherever you arrived informed and well-considered. And certainly for many-- even if they don't embrace his positions with full-throated absolutism, maybe they'll be floating a little more in the direction of his idealisim than it would have without him having him there. And if so, and clearly his principled influence has been influential (and considerably so) for decades, that's a good thing, right? What would the would look like without his constant "impractical" point of view...? Very different, and more scary, I think.
