This is an old paper that is not super meaningful these days. Distributed computing has transformed radically in the past three decades. In the 80s and 90s, there were few useful distributed systems, and we only had a rudimentary idea as to how to build them. Now we run planet-wide distributed systems for billions of users. The lessons from the 90s are no longer very useful.
The vast majority of modern distributed systems are (possibly stacked) client/server architectures, possibly with a significant minority of publish/subscribe systems. And even so, latency, partial failure, and concurrency are still major issues.
