Okay. So I'm reading a short story in one of my back issues of Analog, and I have a complaint.

We all know that light speed delays become significant at interplanetary distances. I say something, then I have to wait for it to get to you, and wait for you to reply back.

And by the time anyone is flying interplanetary distances, I'm sure that we'll all be quite used to video chat, and that we'll finally have videophones.

But I think it should quite clear by now, nobody is going to just sit and wait for the delay.

Right? It's IM, not a phone call. As soon as the delay gets to be more than a few seconds, communication is asynchronous, and you start multitasking. So when the captain of the spaceship is having a tense exchange with some politician back on the ground, he's not going to say a single sentence, then sit there uncomfortably in front of the camera for six minutes while the radio waves trudge back and forth.

It'll be like this: he works on something else while waiting for the reply. His wall-spanning video screen goes "bing" and notifies him that he has a new message. He finishes his current task, then plays the video. He thinks about it, plays it again, and only then does he activate his camera and reply. And when he stumbles halfway through, he stops the recording and starts over. When he's all done, he hits "send" and then goes back to doing whatever he was doing. It's like how we manage email or discussions in, say, blog comments.

Heck, you could do it that way right now, right? It's not even in the future, it's right now! So, science fiction writers of the world, this is what I expect from now on! This story was published in 1996, so I guess it can be excused. Everyone else, you're on notice!

*blink* Yes! I had never thought of it like that before, but you're completely right. Thanks! I'll remember this next time I'm tempted to write some kind of cheesy space opera story. :-)

JOhn.

Although, sometimes I *do* just sit and wait for a reply. Context-switching can be expensive, especially if it's something you're stressed about.

Like navrins, I do sometimes find I've been waiting around for a reply when the conversation is important enough that its thread swamps my processing space. And that's me, and I multitask more than just about anybody I know (I suspect that's true of you as well.) I bet a lot of people idle between IMs.

But yeah, the point where the conversation is simply now asynch, end -of-story, is certainly something to be aware of while writing this sort of thing.

Isaac Asimov wrote a story about the time lag, in the 50's I think. I can't remember the title, but it was about some people who get in trouble far out, with a several hour turnaround, and the people at mission control were trying to figure how to increase the frequency of communication. The (very Jewish mother type)mother of one of the scientists overhears the problem, despite being told it's too technical for her to understand, and solves it: Just keep talking. Synch up later.

What!? You don't think we'll have ansibles by then?

In 1996, the best analog you had to this was BBS teletype or unix chat/irc. But, we'd also had e-mail for long enough to be used to this sort of conversation.

I'd just guess the person in question wasn't much of a computer person. :-)

Oh, puhleaze! Wait, why? Don't they have tachyons or some cheesy thing to accelerate the radio waves in sub-supra-sub space? Or is it just the ships that can go into hyperspace and faster than light? I'll betcha that solving the encryption problem to keep the messages safe for light years of space will be harder to solve than the speed of the transmission. At least that's what happened to computers. No, wait... :-P

Well, in this story, it's just interplanetary (space) travel, not interstellar (star) travel. So I can't fault them on the delivery mechanism, just on the behavior surrounding it.
