Concise futurisms

Space travel:
Those who can, will, because those who can't will kill them from fear of intellect, xenophobia and jealousy if they don't leave Earth.

Singularity:
Not the exponential boom of technology beyond our control, but the use of technology to allow direct communication between peoples. Once people connect directly to technology and eachother, discovery and computation will become exponential several times over.

Aliens:
When a generation suffers futureshock in a near-singularity time, the youth will be so different from them that they will truly seem alien. They will look as strange or stranger than the humanoid aliens of our modern fiction. Once humanity is in planetary diaspora, different evolutions at pace will quickly make interplanetary aliens to eachother. There will be a planetary federation, not from discover of the other, but creation of it.

Singularitarians and transhumanity:
The rise of photonic computing will coincide with the rise of brain-computer interfacing, and therefore, singularity. This is a result of the primacy of photonic interfacing with neural systems, far beyond the immediate potential of nanotechnological means. Once this hurdle is reached, quantum computing, biological data storage and dna micro-sculpturing and sophisticated nanotechnology will be possible.

Cities:
As we become more sophisticated at construction, our cities will be progressively more biomimetic and computer-designed. They will be dense and clustered like termite mounds, above and below ground, leaving suburbia to waste away. There will be greater use of inter-building throughways and intercity high-speed transport systems.

Work:
With robotic implementation in much arbitrary work, there will be use for unskilled 'labour' in virtual reality game systems which employ psychological elements of gameplay to guide the player/worker to think about seemingly abstract and fantastic problems, which are just realworld problems translated into game design. (There is a reason game addicts will play to death)

Love:
'Love at first sight' will come to mean a compatibility analysis followed by hormonal and biological modification, not the currently standardised 'hormone analysis' of intuition or lust. As biotechnology improves, genetic compatibility becomes moot; babies can have their immune systems, etc strengthened accordingly and families will become stronger as a result of the 'partner/friend' paradigm.

Evil empire:
Internet speed and internet technology availability in the population are inversely correlated to the potential for a global empire. 'Evil' will be maintained by a sufficient proportion of the paranoid population online, which will stymie any chance of full infiltration, regardless of the entity's ethics.
