The author has indicated a list of three as the current requirement.
3 Learning agility
Future skills are given as
a) Managing Complexity
b) Innovative mindset
c) Dealing with ambiguity.
In my view even now all the six are required in addition to other soft skills like communication, negotiation, conflict handling, leadership etc.
The more the soft skills that a person has in his profile, the brighter are his chances
to get better opportunities.
