This interview with Leonard Kleinrock is split into two equally sized parts. The first part covers the history and roots of packet-switching networks and Kleinrock’s involvement in the field in the late 1950s and 1960s. The interview gives the reader the feeling of a fascinating time when people were working on the realization of a long-term vision based on some basic principles, like distributed control and resource sharing. In the middle part, Kleinrock discusses the ways in which the current research environment and conditions are different from those in that time. In the latter part of the interview, the challenges of nomadic computing and their consequences are outlined in detail, covering aspects of ubiquitous computing, smart spaces, and technology/functional convergence and divergence.

The article is coherent, focusing on long-term visions, and covering both the past and the future. Computer scientists will find it interesting, but it also has the potential to attract readers who are not computer scientists, but are simply interested in the future of information technology.
