Why Don't Older Americans Want Time Machines?

You want a time machine, don't you?

Because one in 10 Americans do—at least that's what they said when Pew Research Center asked what futuristic technology they would like to own.

That's a notable percentage of people, especially when you consider that survey respondents came up with "time machine," unprompted, out of every possible future invention they could imagine. (Naturally, flying cars were popular, too.)

The curious thing is that Pew found people's level of interest in time travel had a lot to do with how old they are. About 11 percent of 30-to-49-year-olds said a time machine was the one futuristic device they'd want to own, but only 3 percent of people older than 65 said so. 

And looking across demographics of the entire study group, people under 50 were way more into time-travel than people older than 50.

Why is that? 

It's not as though time-travel is a concept tied to a certain generation. Such stories have been around for centuries. And a "major time-travel work" has come out pretty much every decade since H.G. Wells published "The Time Machine" in 1895. That's according to Kij Johnson, associate director at Kansas University's Gunn Center for the Study of Science Fiction. She also sees why the concept may become less appealing to someone as she gets older. 

"What do people do when you give them time travel? They go right to the unhappiest moment of their life and they go back again and again and again trying to fix it," she said. "As an older person, there are more of those events. I'm 54. Do I really want to go back to the core terrible experiences and reengage with them, or do I feel like I've moved past them or around them?"

James Gunn, 90, is the founding director of the Gunn Center for the Study of Science Fiction. Gunn says for the first time in his life he can now acknowledge the fact that he won't read everything he wants to read. He'd no longer take a trip to outer space if given the chance. But he would like to revisit his childhood and see his parents when they were young, maybe offer some romantic advice to his younger self. 

"If I had an opportunity to use a time machine, I probably would," Gunn told me. "I'd maybe tell my younger self to be a little more sociable, less bookish."

Later, having given the question more thought, he emailed with more ideas about his itinerary through time. "My older son died of problems associated with colon cancer. I wish I could go back and make him have a colonoscopy as soon as problems began to appear. Or put a light in the hall so my wife didn't fall over our cat in the middle of the night and break her leg. Or [tell] my younger self not to go out golfing with my brother in shorts and get a bad sunburn on my legs... Nothing that would affect the course of life but would avoid pain."
