I know what you mean. I have been watching repeats of QI (the earlier episodes with Stephen Fry). Alan Davies irritates me, but the other guests are generally great. It's such a lovely vibe – bright, clever, funny people talking about interesting things. Now and again you get a really good episode of 'A Good Read', 'The Infinite Monkey Cage' or 'In Our Time' on Radio 4, and there is the same lovely vibe.
Like you, I'm starved of intelligent conversation (yes, I know that makes me sound like an obnoxious twat). I want to talk about poetry and philosophy and art and ideas. For example, I recently read an article about the Voyager space probe. It was launched in 1977 and is now 15 billion miles from Earth. Though it is travelling at 37,000 miles an hour, it won't reach the nearest solar system for 40,000 years. In 300 years, however, it will reach the Oort cloud, which lies on the edge of our solar system and is filled with space debris the size of mountains. When I'd read that, I almost wanted to cry. I don't know anyone who'd be in the slightest bit interested. I'm also reading Bertrand Russell's History of Western Philosophy atm, and, again, don't know a single person I could talk to about it. I don't mean the people in my life are stupid. On the contrary. But they just don't seem interested in anything.
I'm also starved of people who can hold a civilized conversation. I mean people who listen, who smile and nod, who reply to what you've said (rather than waiting impatiently for you to finish and then talking about what they want to talk about). Above all, I long to be around people who can talk objectively, by which I mean people can talk about a subject without bringing it back to them. Social media is turning us all into raging narcissists. So many people treat every conversation as a battle. They've got to beat you in some way – outdo you, prove they know more, disagree just for the sake of it etc.
