Question 1

There have been lots of “End of Moore’s Law” predictions over literally decades. For those in the audience who might still be wondering, what makes the current “End of Moore’s Law” situation one worth paying attention to?

Question 2

It might be tempting to view End of Moore’s Law issues as mostly affecting the hardware portion of the field, with lesser impact on other aspects of CS. What are some specific examples you see regarding its impact on all aspects of CS departments and of the field as a whole?

Question 3

How has your research changed as a result of technology trends like the deceleration of Moore’s Law and Dennard Scaling?

7/19/1616

Question 4

The hope is that new technologies and techniques might emerge to overcome the slowdowns being seen in CMOS semiconductor technologies. What are some of these new technologies, and how might they influence CS as a whole?
