Typically, an entire industry will grow up around
providing support for a critical infrastructure. For example, communications is essential
to modern life and in the 19th
century, the telegraph emerged as the dominant technology
to provide universal communications infrastructure. But, as the volume increases, that
industry must continue to provide scalable infrastructure, by evolving its technologies to
remain economic. The infrastructure will evolve to handle the new demand. If the
current industry does not scale, another industry will take its place as the major provider
of the essential infrastructure.
Healthcare is the largest infrastructure in the civilized world, and its proportion of the
economy is increasingly rapidly as the demographics shifts to an aging population. But
the medical industry is a physical infrastructure, supporting station–to–station interactions
with trained operators. The healthcare interactions take place in hospitals and clinics
staffed by medical professionals such as doctors and nurses.
