Too me Engineering is a team sport, needing people having basic practical skills up to the Ideas Men. Bad enough that Joe Public sometime demeans engineers, surely much worse when we do it to ourselves! One nonsense is believing theoretical engineers are somehow inferior because they're not good in practical situations! Another is believing that craftsmen are inferior because they lack academic qualifications.
For me what differentiates top-end Engineers from most of us is their ability to meet novel requirements by applying a wide range of knowledge including the ability to estimate costs. It's about problem solving.
For example, building a 19th century steamship, the vessel couldn't exist without the practical skills of Iron Workers, Riveters, and many other craftsmen. But craft skills are a dead end; to advance and develop requires others to understand the theory and how to apply it. At root the problem is economic – steamships were bought to make money, in competition with other ship owners. That means developing engines & boilers that achieve maximum range for minimum fuel consumption, propellers and hull forms curved to maximise performance, an affordable structure strong enough not to break due to hogging and sagging in a seaway, and with the loaded and unloaded weight carefully balanced so the vessel neither rolls uncomfortably or capsizes. Also essential that the vessel is adapted to take best advantage of tonnage regulations (which effect tariffs), minimise turnaround times in port, and recover their build and running costs well within the working life of the ship. A great deal of thought was necessary to get this right, most of it done behind the scenes. While riveters were important, they had no work unless the designer was able to come up with a better ship and someone else was able to sell it. And of course, ships being hideously expensive, financiers, bankers and insurance are essential too.
Today, the engineering behind Pharmaceuticals, Electronics, Communications, Computing, Aerospace, Energy, Materials, Entertainment, and Manufacturing is all off-the-scale complicated, certainly more than any individual can comprehend. Keeping it going needs a clever team with multiple mixed engineering skills. Although the future is bright for engineers at all levels, there is one thing to beware. It is the constant need to move with the times. Riveting once provided many thousands of jobs in the UK, now almost none. Desperately hanging on to obsolescent technical skills and methods is disastrous for individuals and the nation.
