I'm sure there's no intention of scaremongering here. And I realize that handing our lives over to technology is something we do on planes, in trains, and every time we attempt to express ourselves in public. We are an oddly trusting species. Somehow, though, there seems a certain joy in controlling one's own destiny behind a steering wheel. When there's no wheel at all, we're at the mercy of someone else's dream. This may have disturbing consequences.
