A factory can buy a new machine in a matter of months. Finding the people able to install it, understand its limitations, maintain it properly and improve the process around it may take years. That is the reality behind the engineering skills shortage. It is not simply a shortage of graduates, nor can it be solved by a publicity campaign showing young people in hard hats.
Engineering capability is accumulated slowly. It passes from draughtsman to apprentice, from fitter to maintenance engineer, from works manager to a younger colleague who learns why a tolerable-looking solution will fail after six months of service. When that chain is broken, a nation may retain impressive inventions while losing the practical capacity to make, repair and export them reliably.
