Transhumanism
To be more than human is to be human.
We see it already: Cosmetic surgery, sexual performance enhancers, sports enhancement substances, various drugs/medicines, etc.
These are but the heralds to the envisioned advances: bodies that don't age, genetic splicing before conception to determine a baby's traits, or during life to alter deformities, super-intelligent machines, augmentations that allow us to interface with machines, weaponry, and information. Nanites that will help us metabolize food more efficiently, thereby allowing for food and water shortages to become a things of the past.
"GRIN" technologies: Genetics, Robotics, Information, Nanotechnology.
Some already exist. Mice have been genetically altered so that they are able to learn faster. A machine that interfaces with the brain was hooked up to a blind man...the resulting images fed to him via electrical signals allowed him to drive a car.
The prevailing thought is that people will invent these things in the coming decades (or prototype precursors to them), and they will be used by some regardless of ethical concerns. So it is in our best interests to start thinking about it before we find these technologies being used improperly, or not at all, when they could potentially improve human life.

So, if you are familiar with transhuman developments, this is where you can wax poetic about states of consciousness and evolution in a post-Singularity universe (if the Singularity is possible, that is).
And if not, talk about how cool it would be to be a bionic human being.
What are the ethics of such a world? Will Luddite conservatives stop the movement before it picks up full steam, relegating it to fugitive status in mainsteam culture? Are the technologies too far-fetched, or will we see them within the century? Will they lead to mutual human benefit or continued and exponential destruction? Discuss...
