Are Our Skills Time-Limited ?

While new technologies constantly broaden the spectrum of skills to be acquired, the question of the adequacy of skills has become critical. For example, the idea that entry into professional life marks the end of training is distinctly out-dated. We now talk of lifelong training, i.e. a continuum between initial training and circumstances where new skills are acquired. What professional training model should be favoured? Should companies play a more important role in defining priorities for skills development? What place should be given to skills across the board? Is there still a place for culture?
