Could The Continuing Advancement Of Technology Create Unforeseen Ethical Concerns?

Naturally.  There are already ethical concerns in question re: Violation of rights due to privacy invasions, the questions as to what constitutes an "affair" if it is conducted online, cheating in the classroom by using technology (this very site receives questions directly taken from exams -- whether they are take-home or in-class one can't determine), the medical ability to keep a person alive with little to no quality of life...  Until we know the direction technology will take, we can't foresee the exact ethical questions that will come into play; but, undoubtedly there will be many.

I'm not sure that they will be unforeseen, but as the other poster said, there will certainly be ethical concerns surrounding any new technology.
