Is the task-force American? Chinese? English? Global? Were the members picked from the world's best, or were they recruited like for any typical job? Were they chosen from any specific geographic area? Members of the team are a globally selected unit of elite.
Did the members apply to join, or were they set invitations? If they were sent invitations, was there then a sort of testing/interviewing process? They are a secret task force that specializes in averting world disaster.
What is the world like? Is nanotechnology available everywhere? Do only the rich have it, or can anyone get some? In 2018, the world is becoming populated with more and more nanotechnology, though the distribution of it is largely confined to first world countries and rogue groups that have acquired some of the new advanced technology for use.
Is the world unified, or do countries still exist? Are there any ongoing political or military struggles? Countries still exist largely as we know them today, although the lines are more blurred between G20 nations. In particular, Europe (including the UK, Scandinavia, Ireland, etc. as well as Continental Europe), Canada, USA, Australia, and New Zealand have all come to some sort of economic consensus to help drag the world out of a massive economic recession. China and Japan are also very close to this alliance and share in much of the benefit, although Hong Kong is becoming a bit of a problem. There have been threats from Kowloon in particular that seem to indicate a possibility of world-wide "cleansing". In this reality, Hong Kong has never set about (historically) to achieve the demise of the Walled City of Kowloon. The 2018 crowd will be attempting to bring about the reality of its destruction as we know it today.
Are there still the equivalent of today's third-world countries? Yes, and they are primarily the same as they are now, although there may be some rogue groups with higher technology. Similar to today where a remote village in the desert may have satellite phone and internet access, the same sort of people would still have greater technology in 2018, but more of it would be nanotech. This includes Kowloon in 2018.
What are the education systems like? Education is moving more toward online degrees and even internet secondary school. Around half of students are receiving diplomas without ever setting foot on campus.
When was nanotechnology first developed? http://en.wikipedia.org/wiki/Nanotechnology#Origins
What milestones were there in the development? http://en.wikipedia.org/wiki/Implications_of_nanotechnology Some of these issues are still importantly unresolved. It is a source of debate worldwide as those who are speaking out in 2010 finally become heard in 2018 about the dangers posed by nanoparticles becoming released freely into the world.
When did various countries/areas have nanotechnology widely available?Nanotechnology is already in large stages of production and gradually increases like a graph of a square root:
When, if ever, was nanotechnology development taught in schools/colleges?Nanotechnology in 2010 is largely developed by university students and their professors. More and more becomes developed by private, capitalist organizations so that by 2018, nanotechnology is primarily developed by businesses with the same disregard for consequences that modern single-use product manufacturers have for the long term effects of their efforts. As with any education, slowly over the years, only the very basics of nanotechnology (primarily the good parts) filter down through the pre-collegiate education system, which is still fallaciously promoting the existence of a dinosaur called Brontosaurus.
