I’m reading (listening to, actually) Superintelligence by Nick Bostrom and finding it unexpectedly very interesting. The book focuses on artificial intelligence, but early on he talks about possibilities for enhancing biological intelligence using current or near-future technology. Here’s an online paper where he talks about the same concept. Just using current in vitro fertilization technology, which creates about 10 embryos at a time, you could theoretically boost IQ by about 11 points if you pick just the smartest of the 10. (This is just a thought experiment so let’s not worry about the other 9. Of course, some otherwise reasonable people are going to have an ethical problem with this.) Do that 10 times in a row and you could theoretically boost IQ by 100 points or more. Einstein had an IQ of about 160. So you can produce a race of super-Einstein’s using current technology. Now, it would take 250 years to do this, and you would have to get everybody to do it, both to make a real impact at the societal level, and to avoid disturbing implications of those left behind.

Using a likely near-future technology called iterative embryo selection, you can theoretically extract the DNA from one or more embryos, move it to sperm and egg cells, combine them again to make a new set of embryos, and do it again. This might take a few years or months to go the 10 generations of 1-in-10, rather than 250 years. Now it’s potentially something big.

I’m a bit worried about super-villains. I don’t see any reason to think twice-as-smart humans will automatically be twice as ethical or twice as empathetic, and it might only take one really bad apple to ruin whatever utopia our newly brilliant problem solving selves come up with.

Like I said, the book is really about artificial intelligence. He believes that even humans enhanced to have, say, double the current average IQ will eventually be far outclassed by machines. It is not going to take 250 years for that to happen, so creating smarter humans in 250 years won’t make a lot of sense. If we create smarter humans in the short term, he thinks they will just use their smarts to make smarter machines even sooner.

This is just scratching the surface. It’s really a fascinating book, and somewhat like when I first read The Singularity is Near, I kind of feel like I am being let in on secrets that nobody else around me knows.
