Umm, air pressure is only an issue if you open the door - which you wouldn't want to do on Venus anyway, unless you want to die of carbon dioxide poisioning.

Unlike needing a full pressure suit, think scuba gear and a protective layer. The temperature at 52km is a bit chilly at 13C / 55F, but it is in many respects a lot more hospitable than a space station in orbit.

Meanwhile the atmosphere offers plenty of CO2 and some nitrogen, but no hydrogen aside from the paltry amount in the 25ppm water vapor,

The clouds are made of sulfur dioxide - (SO2) which produces a sulfuric acid rain (H2SO4). So, mining that rain gives you H2O, or O2 and H2. In the absence of atmospheric oxygen, you can safely use H2 as your lifting gas, and not have the leakage problems that using monatomic helium gives.

Or you can look here.

which, theoretically, will require an increase in aggregate labour inputs.

But that's no longer true when you can increase production and lower labour at the same time, and everyone else in the supply chain is doing the same.

At some point, the surplus labour cannot be retrained to do "new" jobs because those jobs either already have a surplus of labour, or no longer exist, or they exist, but they're also automated.

At that point, "retraining programs" are just make-work projects (not to say that they mostly aren't already).

The more machines steal our jobs from us, the less we have to work and the more we can spend out time doing fun stuff. Isn't that what automatisation is all about anyway?

That would work if the "less work" was split evenly among everyone who wanted to work - then they would have the money to do fun stuff in their free time.

That hasn't happened. Productivity has doubled in the last 40 years, but real wages are stagnant, and the average work week hasn't gone down for those who work.

The worst part is that this trend is going to accelerate in the future, and more technology won't "fix" that.

The one thing overlooked wrt self-driving cars and other pervasive automation is that they will reduce demand for themselves as well. Who needs (or can afford) a self-driving car if they've semi-permanently become jobless through automation, and it's cheaper to take a self-driving taxi once in a while?

And who needs the office? The "virtual office" with "virtual secretaries", "virtual bookkeepers", "virtual sales staff", "virtual everything" will just be bits on a server somewhere. So all the associated jobs that kept that office tower running will cease to exist as well, so even less demand for self-driving cars to get to and from work.

That leads to the lessening of value of "prime office real estate," and all the knock-on effects that will have. So those robotic floor cleaners that did the office tower floors are now out of a job as well. Ditto the cafeteria robots, the toilet cleaning robots, etc., until those prime office towers are converted to - guess what - slum housing.

And since everything will be within walking distance, none of those "city-dwellers" will need self-driving cars, even if they could afford them.

Yeah, he got succeeded by his brother. Wonder what is it about Commie countries nowadays? They started off by overthrowing monarchies wherever they could find them - Russia, Egypt, Libya, and so on. Nowadays, every surviving Communist country has de facto dynasties - North Korea, Cuba, Syria. If only the Romanovs had known and maneuvered to take over the Communist party, they may have saved themselves from getting massacred.

George H. W. Bush, George Bush, and now Jeb Bush trying for the job. No de facto dynasty there :-)

The problem is that as aging is not a disease anti-aging pills are not medicines and are much easier to put on the market. I'm not sure whether aging should be seen as a disease or not by the legislators, but at least it would put an end to these scams.

First definition of disease:

a disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury.

Aging IS a disease, and a fatal one at that.

And yay, it shall come to pass that scientists will no longer interest themselves in saving lives and making the world a better place and shall instead devote their attention to preventing hair loss and prolonging erections... and delaying the effects of aging, "leaving your skin feeling visibly younger."

Doesn't match the facts. They were looking for ways to have less internal scarring on major blood vessels, and now their first product will be to treat lupus.

Lupus is a chronic inflammatory disease that occurs when your body's immune system attacks your own tissues and organs. Inflammation caused by lupus can affect many different body systems — including your joints, skin, kidneys, blood cells, brain, heart and lungs.

Lupus can be difficult to diagnose because its signs and symptoms often mimic those of other ailments. The most distinctive sign of lupus — a facial rash that resembles the wings of a butterfly unfolding across both cheeks — occurs in many but not all cases of lupus.

Some people are born with a tendency toward developing lupus, which may be triggered by infections, certain drugs or even sunlight. While there's no cure for lupus, treatments can help control symptoms.

There's more ... lots more.

Or deploy it at a slightly higher (or even lower) price and eat the competition alive. So, when the patents expire, who's left standing? And that gives you lots of money to spend on further research to improve the product, as well as the biggest marketing budget.

If you want to do manned flights, orbital stations have a few problems. There's the lack of air pressure, lack of anything exceeding microgravity, and extremes of heat and cold at the same time. Also, in orbit it's not possible to tap the sulfuric acid clouds to get the essentials - water, oxygen, carbon, and hydrogen. Plus there is reason to believe that microbial life of some sort exists in the clouds.

Nobody's gonna believe that computers are intelligent until they start coming in late and lying about it.
