When the world gets me down, I escape a little by imagining what life will be like in the future. Anyway I suspect a one-world, just, peaceful government will form on earth 2160 A.D. The timeline just makes sense. Plus it is the approximate time given in the fictional Star Trek universe. Heck, I'll even give you a date. February 2, 2160. I doubt if much will happen that date. But the ancient Celts called it 'Imbolc': the first stirrings in the womb. So I like that date. No money. No wars. Not a single poor or homeless person. Think of John Lennon's song 'Imagine'. So when do you think it'll be? Give a year prediction. And heck, give a date too. Why not? I'd be interested to see what you guys come up with.
Never. Sorry to poop on your parade, but most people are too stupid and selfish to actually let this happen. In this current arrangement, somebody always wins and makes profit. In their eyes, they're not gonna give up their privileged positions to allow "some bums" to get free shit, and an actual voice. As depressing as it sounds. (But hell, prove me wrong. I won't mind.)
I'm working on the networking systems logic to make it happen. Basically, the world economy is run by banks that all use the same Three Stooges approach of cutthroat poker, and you have to leverage quantum mechanics to encourage them to eat each other alive. For example, almost half of all Wall Street transactions are now handled by computers, and I want to make that closer to 100%, by making the machines smarter than people, which is easy, since machines can actually tell the difference between a lie and the truth, and have no need to lie to themselves. Feeding idiots all the lies they demand and customizing them to the individual is nothing new, but the trick is to make it the most wildly efficient and cheap. Essentially, the truth cannot be conquered, but you can't convince Wall Street of that, so its good money. It has to do with your immune system and reproductive system, which should prove extremely interesting.
not long after the species human comes within an inch of destroying itself by ignorance and indifference to its dependence on the diversity of its world's environment.
One world government would no doubt result in one world dictator. If there's one thing I learned from this past election, it's best to have states decide their own elections. Similarly, it's best to break governing bodies into autonomous or semiautonomous countries, states, counties, and cities because there's no way to prevent unjust actions by corrupt, power hungry leaders, but you can limit their damage by limiting their control.
I think if the U.S., China, & Russia were to align in mutual interest that might make a really big superpower. But I think you'd still have middle eastern countries who want to run their own countries. Maybe Africa and Australia could unite too. South America needs more attention from the northern hemisphere I think.
shortly after open relations with people form other worlds that have one. i think most people have an unrealistically narrow idea of the diversity of forms such a thing might take. it really depends more on cultural consensus. when people equate thoughtlessness with freedom, then of course they're "asking for" totalitarianism. but a majority opposite of that is not at all unlikely. a world government could be completely or almost completely "service state anonymous" mostly out of sight out of mind and really almost not reason to notice its there, other then the role it could play in preventing nationalist authoritarianism. where only your local village can pass a law that affects your life as an individual, and broader levels of governance, up to and including a planetary federal union, exists primarily to protect things like your freedom of movement, environment, infrastructure, and tans-galactic trade.
I can't see that ever happening. Just look at democrats and republicans. Each calling the other the bad guy. Other countries are not going to let one world order tell them what to do.
Sorry to be pessimistic as well, but I think we as a species are too aggressive and territorial for that to ever happen. The Soviet Bloc broke up, Yugoslavia broke up, the UK became devolved, Sudan split in two, the EU lost one of its' biggest members. I think the trend is to smaller states rather than bigger ones.
