Perfect eyesight. Curing cancer. Designer babies. Super-soldiers. Because of CRISPR, genetic engineering might make tinkering with life as easy as playing with Lego.
Imagine you were alive back in the 1980's, and were told that computers would soon take over everything -- from shopping, to dating, and the stock market, that billions of people would be connected via a kind of web, that you would own a handheld device orders of magnitudes more powerful than supercomputers.
It would seem absurd, but then all of it happened. Science fiction became our reality and we don't even think about it. We're at a similar point today with genetic engineering. So let's talk about it.
Relatedly, I'm finishing up Neal Stephenson's Seveneves right now and while it starts out as space science fiction, much of the book is concerned with the sort of genetic engineering issues discussed in the video.
Microsoft founder Bill Gates, in addition to attempting to save the world, is also a voracious reader. He recently recommended five books that you should read this summer. On the list is Seveneves by Neal Stephenson, which I might finally try, having absolutely loved Snow Crash and Cryptonomicon when I read them a few years ago. Gates also recommends Yuval Noah Harari's Sapiens, which I read earlier this year and think about every few days. I wrote a bit about Sapiens and the invention of farming, which is a topic about which Gates disagreed with Harari.
Neal Stephenson has made the first 26 pages of his upcoming book, Seveneves, available on his website. About the book:
A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space.
But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain...
Five thousand years later, their progeny-seven distinct races now three billion strong-embark on yet another audacious journey into the unknown... to an alien world utterly transformed by cataclysm and time: Earth.
The novel is out on May 19.
Update: Seveneves is now out and getting some good reviews on Goodreads. Get it while it's hot.
Neal Stephenson leads us through a short history of the rocket, from Hitler to the Manhattan Project to Stalin and then the space program.
The phenomena of path dependence and lock-in can be illustrated with many examples, but one of the most vivid is the gear we use to launch things into space. Rockets are a very old invention. The Chinese have had them for something like 1,000 years. Francis Scott Key wrote about them during the War of 1812 and we sing about them at every football game. As late as the 1930s, however, they remained small, experimental, and failure-prone.
A rocket taking offThere is no way, of course, to guess how rockets might have developed, or failed to, were it not for the fact that, during the 1940s, the world's most technically sophisticated nation was under the absolute control of a crazy dictator who decreed that vast physical and intellectual resources should be hurled into the project of creating rockets of hitherto unimagined size.
