Many of these problems you mention are due to empires past imposing borders that don't correspond to natural nations. Most of Europe's borders are pretty natural equilibriums settled after centuries of wars. They are not perfect though so we are now seeing secessionist movements across the continent. Demographic changes and migrations flows threaten to upset these equilibriums. Africa and Middle East have different problems since their borders are more artificial and imposed from the outside. Most of these regions of the world can barely hold together a cohesive government without outside help.

The main reason the Scots like the EU is because the English don't like it.

Global city-states need to become independent with open immigration, separate from the Nations which should enforce strong immigration controls to maintain the native population & culture.

Looks more like Facebook than a forum?

I think there was a time when it was once considered a vaguely normal blogging platform.

It's abnormal now?

A spider web, obviously ;-)

You don't need an add-on for that... just right-click, 'Inspect Element'

I would also recommend Book Depository: http://www.bookdepository.com/

Which is actually owned by Amazon. But I don't know how much they cooperate internally.

Moore's law has not been an exponential increase in technological capability in general. It has only been an exponential increase in one particular technology - more of the same. I see no evidence that the development of novel technology in general has sped up in any way.

No technology has ever extended life. The so-called gains in life expectancy have only come about by reducing the causes of early mortality and slowing down the diseases of ageing.

I'm not the commenter you're replying to, but maybe they meant that we've only reduced early causes of death like disease etc, but not done anything to affect our internal biological processes that cause aging. As an example, reducing skin cancer by staying out of the sun keeps you from prematurely aging, but it doesn't stop your hair from turning white and your wrinkles from forming.

Drugs that change our metabolism can affect how much damage something does to your body, and you die because your body systems fail or degrade. So fixing some causes and symptoms should be able to increase your possible lifespan. Just like we can increase the lifespan of some simple animals, we could increase our lifespan through physical means. There's no magic spirit inside you that can only last 120 years, as far as anyone knows.

Today you can be healthier at 1, 20, 40, 60, and 80 than you could have been 100 years ago.

However, just like 100 years ago, you will almost certainly be dead by age 100. For certain by 120.
