Technology is advancing at an exponential rate often called the "Law of Accelerating Returns." If futurist predictions prove correct, we'll have advanced molecular manufacturing by around 2025, and possibly the replacement of humanity by vastly advanced machines a decade or two later.
This is a chronicle of our journey to that future, one advancing technology article at a time. I post the more significant and interesting articles as I come across them.
I grew up with Isaac Asimov's "Extraterrestrial Civilizations." It's the original "Rare Earth hypothesis" which those writers fail to mention. There was an article recently(like a week or two ago) that Pete Ward and Donald E. Brownlee are making a second edition, because, of new theories about the origin of life.
They talk about this new theory of life of land getting periodically wet and dry, as if that's somehow going to make the origin of life. I would think you'd need a continues process. Really, they just don't like the idea of life originating in the ocean vents because understanding how life could have gone from non-life down there is too hard for them to imagine. Note - if life is found on Enceladus, that's points to a sea vents origin of life here on Earth. Beyond that, there was recent articles of a water Earth for millions of years. For like five hundred million years or so. Anyways, I recently wrote a blog article after recently re-reading Isaac Asimov's "Extraterrestrial Civilizations", and some recent work about, i think the element phosphorus being produced only by certain supernova and not others.

I will, of course, have to post this new article about stars giving enough energy to make for photosynthesis in the replies section.
