But the new "Westworld" is airing at a time when we're not only more comfortable with our machines and devices, but have integrated them so thoroughly into our everyday lives that they're more like extensions of us than mere utilities. For the humans - both on screen and off - the fear in "Westworld" isn't a computer glitch, but the worry that technology will evolve past us, resulting in synthetic creations that are stronger, smarter, more durable and perhaps worthier of occupying space on Earth. In this future, it's people who are the crude, malfunctioning machines, destined for the scrap heap. Earth 2.0 doesn't need us anymore.
