2What will nanotechnology bring?
- A spectrum of views extreme predictions, modest
predictions, and in between
3Extreme predictions the hype
- Immortality!
- Godlike powers!
- Nanobots inside us curing all diseases!
- The ability to build or remold anything,
including ourselves, from the atomic level up!
4Extreme predictions the hype
- Or on the gloomier side out-of-control nanobots
devouring the earth!
5Extreme predictions Drexler and Kurzweil
6Extreme predictions in ficiton
7More modest predictions
- Fancy nanoengineering wont work!
- 1. Too sticky
- 2. Brownian motion
- The most we can hope for may be .
8Modest predictions
9What will nanotechnology bring?
- Most nanoscientists think the truth lies
somewhere in between - which is pretty exciting!
10Even on a moderate view, nanotechnology raises
issues of ethics
- How should we balance public welfare and safety
against academic freedom of researchers? - How can we compare the weights of national
security, corporate profit, public good,
individual rights, environmental impact, and
integrity of scientific enterprise?
11Even on a moderate view, nanotechnology raises
issues of ethics
- How should the benefits of, and/or the control
over, nanotechnology be justly distributed? - What are the ethical implications of altering
human nature via nanotechnology?
12Thinking About Ethics
- Ethics is a branch of philosophy.
- What is philosophy?
- Subject matter questions about the ultimate
nature of reality, knowledge, value - Method dialectic reflective equilibration
13Three Main Branches of Philosophy
