Committing a guy for writing a book is many things, but it ain't fascism.

You're right, of course, and I should have made clear that is not what I was saying in the first place. What I wish to convey is that the USA abide by all eight core tenets of classical fascism, as detailed by John T. Flynn, and have done so for a long time. Abuses of police power, attorney power and executive power as seen in the article (and others) are but an inevitable consequence of the first two tenets.

There is more than one way to do it.

This one is real though, 16 meters (52' and a half) long, 60 tons and seven days of underwater autonomy. No idea what's the price tag though.

Well, there is a word that defines accurately what is happening here, but because this word has been slowly stripped of its rich meaning and turned into an empty slur, most people have stopped using it appropriately, instead merely employing it as a slur. For shame, really, because its attached historical lessons are desperately needed these days.

The idea of a "personal submarine", IMHO, should be more along the lines of this kind of thing. Just build it yourself !

the animals themselves were lean animals

Do you mean lean like wild american buffalos, camels, et al. who pretty much all have a huge slab of fat on the back ? Or lean like salmons and whales and seals, with fat packed under the skin ? Also, they always ate the brain and bone marrow, which are almost pure fat too.

Also, people during that age were not especially healthy. They probably died in their 40s.

Wrong. Half of them died young (typically before the age of 5) and the rest lived to their 60s and 70s, sometimes even older. Reconstructed modal age for primitive hunter-gatherers is 62 to 64 years of age.

There is a marked reduction in average size, and sudden appearance of generalized tooth decay, traces from infectious diseases and formerly absent bone deformities in our record of skeletons from the paleolithic to neolithic transition. Granted, the infectious disease became more widespread because of the growing densities of populations at the time, but the rest has been determined to come from the evolution of the diet. There is also a reduction of serious injuries observed, because less hunting decreased the exposition to dangerous predators and hunting accidents.

As for life expectancy, it decreased slightly with the agricultural revolution until circa 2000 BC, at which point advances in hygiene, sanitation, productivity and trade compensated for the difference. And we only now have caught up the loss in average height. There has been evidence of an adaptation to agricultural diets over time, but its effect is still small in terms of life expectancy.

I wonder if similar critters could survive in the liquid methane lakes and rivers of Titan ?

Economists say it is impossible.

Citation needed.

Maybe instead of automating the grunt work, we need now to automate the automating itself, so that the high-tech tools become just as cheap and prevalent, affordable to every small-scale farm, as the food grown with those tools.
