It looks as if I'll have to wait until next week to post a Ten-Word Tuesday, as there's other interesting topics to discuss.
Long-time readers of science fiction may be familiar with Vernor Vinge's concept of the Singularity, a time when computers meet or exceed human intelligence. Some computer scientists now think that if the current rate of technology improvement continues, we could reach this point in 2045. (Click here to read the article in Time.) I'll be 75 in that year; my son will be 38. It's entirely possible that we'll all live through this history-changing event, especially if life-extension technology, such as treatment with telomerase, an enzyme that repairs the ends of chromosomes, becomes widely available.
You can find a list of science fiction books dealing with the Singularity here, though I'm sure it's not complete. Science fiction writers have foreseen varied fates for humanity after the Singularity, everything from us uploading our consciousnesses to computers and exploring the galaxy to humans being enslaved or killed off by superintelligent computers who don't need us. It's hard to predict what will really happen, especially when other factors, such as climate change, resource scarcity, and natural disasters or wars may throw off futurists' predictions. That's why the article in Time says that if you want to know what the world will look like in forty years, "You have to think very, very far outside the box. Or maybe you have to think further inside it than anyone ever has before."
Other than your retirement funds, how are you preparing for the next forty years?
