How serious are these problems?
Does the internet make people narrow &unsocial?
Is working on a computer more isolatingthan reading a book, an activity that isusually applauded?
Is the internet destroying communities?

MAKING DECISIONS ABOUTTECHNOLOGY
-
8/14/2019 Evaluating and Controlling Technology31-7.ppt
43/44
Each new technology finds new and unexpected uses
The history of technology is full of wildly wrong predictions
Weizenbaum argued against developing speech recognitiontechnology
Mistaken expectations of costs and benefits
Should we decline a technology because of potential abuse
and ignore the benefits? New technologies are often expensive, but costs drop as
the technology advances and the demand increases
The Difficulty of Prediction:

Intelligent Machines and Super-intelligentHumans - Or the End of the Human Race?
Technological Singularity - point at whichartificial intelligence or some combined
human-machine intelligence advances so farthat we cannot comprehend what lies on theother side
We cannot prepare for aftermath, but preparefor more gradual developments
