Exponential growth in the non-mathematical physical world (i.e., with limited resources) is just temporary..

@studiotThere are different 3D printing technologies. Fused deposition modeling (FDM) is the most common and is what I use. I don't see mention of technology they used. Clickbait for newbies. "Everything" around you, that is less than 5 years old, was 3D printed at some point by engineers creating a prototype of the thing in question. I have 3D printed vodka glasses.. FDM is good for the environment. You can take the plastic PET bottle and convert to filament that will be used for 3D printing. This means you use up the plastic you buy everyday and have free filament for 3D printing. Add in solar panels and you have a machine that runs completely for free.. There are two main techniques: 1) using a hotend from a 3D printer to heat a PET bottle to make the filament, 2) use gluegun for the same effect.. So you could go to a landfill and find enough PET bottles to make whole rocket body for free..

Maybe more addictive, but your point is sound. Primary difference I see is where data is hosted and consequently how it gets protected / exploited. This takes nothing away from your crisp question, though. A lot of this is modern day Cold War drum beating.

In fairness it would be hard to call Avi Loeb a confused individual. His bio at the bottom is worth a look. That's an interesting blog, on Oumuamua. The anomalous acceleration of that chunk is really needing further study. As @Moontanman notes, real scientists are debating possible ways this might have occurred. The odd cutting out of the New Horizons probe in the Kuiper belt is also an anomaly - we should at least be open to possible ways such an object as Arawn could generate an EM interference strong enough to jam the signal - it doesn't have to be an artificial source to be worth investigating. Any explanation would likely advance our knowledge of the KB. These don't seem like Bigfoot tracks that bored teenagers made with size 16EEE (EU 52, roughly) party slippers.

Not necessarily. Fundamentally evolution is just a change in the gene pool over time. In order for it to happen one would need a situation that fulfils the Hardy-Weinberg equilibrium. Which also includes no sexual selection, sufficiently large population to eliminate stochastic effects and so on.

AFAIK, x2 has two square roots: +x and -x.
