Trains, they had style, a vision of the future with curves and wings and any assortment of unimaginable coolness. What do we have now? Minimalism. We can't even take the time to put effort into our work, every stove is like every other, every car like every other, a box for a home and a little square window and a little square door.

would be in our future. Unrealistic? Sure, functional? not in the slightest. Visionary? You bet. Jules Verne gave us the Nautilus and we returned with an oversized piece of pipe.
I'm not sure what we'll develop in the future, but when it's going 150mph, and looking lame will make it go 155mph instead, give it some style and put in some real craftsmanship instead. Screw the extra 5 mph.
