You have missed the point. The things we take for granted today started small and evolved from there; we have merely added a lot of superstructure to the underlying bedrock foundations envisaged by these select pioneers. All the application layer protocols and technologies utilizing them can be replaced as the fad changes (eg. distributed Objects vs. distributed web) but these core concepts/ideas/technologies will always remain and hence needs to be acknowledged. The situation is analogous to the building of great Architectural Marvels; even though a lot of folks with different skill sets are actually responsible for the manifestation, it is usually the "Architect(s)" who are credited with the achievement because it is the keeping of the holistic design together through its evolution is what is actually the key.

"Kids" nowadays don't even know of the true "Greats" who made The Internet as it is today, possible (they have forgotten "standing on the shoulders of giants"). I always point folks to the classic early-1990s Internet System Handbook by Daniel Lynch and Marshall Rose which explains the then Internet Architecture with chapters written by the greats like Jon Postel, Vint Cerf, Van Jacobsen etc.
