Socialism is not about workers. According to the definition in Wikipedia: "Socialism is an economic system in which the means of production are commonly owned and controlled cooperatively; or a political philosophy advocating such a system.". Applied 19th century and early 20th century industrial society, this may have meant empowering the large masses of workers. Applying socialism to a world where robots do most jobs would just mean that everyone gets to share the robots and the results of their labor. People could fill their time educating themselves and doing philosophy, science and creating art.

Then it's not really work.

Actually, it depends on the energy and, for low energy objects, on how high the lowest point in their trajectory is.

By energy, the objects can be classified into:

1) Objects with lower energy than the Earth's gravity well. In ideal conditions, these objects would orbit our planet forever in an elliptic trajectory. In reality, all of these will fall out of orbit because of friction (since there is no perfect vacuum). The time to fall out of orbit depends on the how far away from the Earth is the lowest point of their elliptic orbit. The closer their elliptic orbit gets to Earth, the quicker they will lose energy because of friction with the atmosphere.

2) Objects with high enough energy to escape Earth's gravity well. These head out into space.

It depends on how you define "god". The likelihood of existence is different for:

1) An intelligent creator of our known universe. (Equivalent to our known universe being a simulated reality)
2) An intelligent creator of our known universe, attempting to communicate with us.
3) The intelligent creator as described by the various holy books, with all the details.
4) A being outside our known universe, replacing teeth children hide under pillows with money.

Yes, we've had and we still have widespread non-commercial sharing of software and music, but it was never legal.

By making non-commercial sharing legal, all content creators trying to sell their work will be in a competition with companies specialized in providing free and easy access to non-commercial content, which will now be 100% legal. I don't think the content creators will be able to do more than ask for donations.

What about works where almost all use is non-commercial?

For example, what should professional musicians do, only record advertisements?

Or computer games - I can't imagine a business model that would work for them if non-commercial sharing was allowed.

The power outage you experienced lasted less than 2 days. That's not enough to exhaust supplies in supermarkets.

The scenario presented in TFA talks about a power outage that would take months to be repaired. And would happen everywhere at the same time. It's a very different situation. For example, I wonder - is there enough equipment to transport drinking water for everybody?

Because the extra pollution you make affects everybody else. I know the extra carbon _you_ are responsible for is an insignificant amount on a global scale, but if many people think like you, it becomes a problem. It's similar to the issue of smoking in public places, but on a global scale.

Considering where the world economy is currently headed, I wouldn't worry that much about outsourcing. China's economy is most likely going to rise relative to the US economy. So engineers in China will keep getting more expensive, and engineers in America will keep getting cheaper.

Hint to slashdot mods: all the examples are reversed.

You're part of a lucky few. For most people in the world it is hard even to pay a short visit to the USA, because we need a visa that isn't easy to get.
