From that interview:
Q4: What is the future of Agile?
First we will drop the capital A. Then we will drop the term "agile" altogether. Agile methods will be successful if and when we stop seeing them as anything other than normal, sensible, professional methods of developing software.
That even someone as renowned in the field of "conventional" software development as Jerry Weinberg points to the common sense embodied in these methods makes me hope that someday the waterfall-style methods might vanish alltogether.
