Totally agree, figuring out how to build machines by coding in DNA is the next frontier. A bit scary since we don't know what we'll figure out. What if someone writes some code for a virus that wipes all land animals. There are bacteria that survive in space for a period. Earth could easily have been seeded by outerspace bacteria with DNA. Carbon, Hydrogen, Oxygen are not rare elements in the Milkyway. If the ingredients are plenty, why isn't there intelligent life booming in the galaxy. Plausible reason: after a certain amount of intelligence, the species becomes unstable and self destructs.
