“We Can Put Unlimited Numbers Of People In Such Engineered Environments”

In a Phys.org piece, astronomer Seth Shostak identifies the twenty-first century as the last one that may be ruled by Homo sapiens, with speciation being driven by three huge changes. Perhaps it’s surprising the writer believes humans living on other planets won’t be altered as radically as those on Earth engineered by General Artificial Intelligence. My bearish mind thinks 85 years is a very aggressive timeframe for what he proposes, but nothing about it seems theoretically impossible in the long run. 

An excerpt:

To begin with, we’re finally going to understand biology at a molecular level. DNA’s double helix was discovered a mere six decades ago, and now – for hardly more than a kilobuck – you can sequence the genome of your yorkie or yourself.

The relentless interplay of science and technology ensures that genomic knowledge will spawn a growing number of applications. Curing disease is one of these, and it’s obviously desirable. But our efforts won’t be limited to merely fixing ourselves; we’ll also opt for improvement. You may hesitate to endorse designer babies, but hot-rodding our children is as much on the horizon as the morning sun.

Number two on my list of major developments is expanding into nearby space. We need more resources – both acreage and raw materials – unless we’re happy to condemn our descendants to a limited lifestyle and unlimited war. You may worry about running out of oil, but that’s not the resource that should really make you antsy. We’re going to eat through the easily recoverable reserves of stuff like copper, zinc, and the platinum group metals in a matter of decades.

We can find more of these elements in asteroids, and already several companies are planning to do so. But nearby space could also provide unlimited real estate for siting the condos of the future. Everyone expects our progeny to establish colonies on the moon or Mars, but the better deal is to build huge, orbiting habitats in which you can live without a spacesuit. Think of scaling up the International Space Station a few thousand times. We can put unlimited numbers of people in such engineered environments, and sometime in this century we’ll start doing that. The days of being confined to the bassinette of our birth are coming to an end.

The third thing you can expect before the year 2100 is the development of generalized artificial intelligence (GAI). In other words, machines that don’t just play games like chess or Jeopardy, but can do the thinking required for any white-collar job, including all the ones at the top. And such machines won’t necessarily be large. A synapse in your brain is a few thousand nanometers in size. A transistor on a chip is hundreds of times smaller. The hardware necessary for human-level smarts – even today – could fit in an iPad.•
