This is TALK OF THE NATION. I'm Neal Conan, in Washington. Technology's already changed our lives in ways we couldn't have imagined just a few years ago, and now seems ready to reinvent our future. As we continue our series of conversations looking ahead, we've invited Farhad Manjoo to join us - he's Slate's technology columnist and a frequent guest on this program - on the latest gadgets, on the business of consumer electronics and on how we've adapted our lives, our jobs and our manners to all these changes.
Now, you've probably noticed this. Political drama is not confined to just the news on TV these days. We are in an era that is seeing a proliferation of politically themed television and other forms of streaming. And maybe you've also noticed shows like "Veep."
