Craftsmen and other practitioners have always been bitterly needed, theorists are only needed to a very small extent, just like managers, while nowadays we train almost everyone as to be a manager or (applied) scientist ("theoretician"). Of course, ICT can be interpreted as applied theory, but then again, ICT can do a lot, but we still need to build roads and houses, etc. The point is that training and work may also alternate from around sixteen, that it is a “dogma” that all training must first take place and that only then people may start to work. Especially in a rapidly changing world, such dogma is enormously outdated.
