Rapid advancements in the use of machines to augment human intelligence are creating a
new reality in which we increasingly interact with robots and intelligent agents in our daily
lives, both privately and professionally. The list of examples is long, but a few of the most
common applications today are found in education, health care, maintenance and gaming.
My vision of the future network is an intelligent platform that enables this new reality
by supporting the digitalization of industries and society. This network platform consists
of three main areas: 5G access, automation through agility, and a distributed cloud.
A set of intelligent network applications and features is key to hiding complexity from
the network’s users, regardless of whether they are humans or machines.
The ability to transfer human skills in real time to other humans and machines located
all around the world has the potential to enable massive efficiency gains. Autonomous
operation by machines with self-learning capabilities offers the additional advantage of
continuous performance and quality enhancements. High levels of cooperation and trust
between humans and machines are essential. Building and maintaining trust will require
decision transparency, high availability, data integrity and clear communication of intentions.
The network platform I envision will deliver truly intuitive interaction between humans
and machines. In my view, there are five key technology trends that will play critical roles
in achieving the vision:

TH E Z ERO -TO U CH networks
of the future will be characterized by
the fact that they require no human
intervention other than high-level
declarative and implementation-
independent intents. On the road to
zero touch both humans and machines
will learn from their interactions.
This will build trust and enable the
machines to adjust to human intention.
