Admittedly, the author mentions "near future", but I am not sure that this is a very contentious perspective and I think we are already there. I believe both in terms of what organizations look for in leadership characteristics, as well as the technology to connect already being widely implemented, even if it hasn't yet firmly taken hold. The latter is for reasons of change management as much as it is a question of technology.

A good example is King's Fund, which has put resources into creating a global network of health professionals, as well as LinkedIn. Neither has terribly significant traffic yet, however, or is considered to be essential to work and the gestation of ideas.

Once true, practical value is perceived from the employment of the technology, we will see its benefits, but not before. This will still take a few years (not too, too many).
