This might be a case of a technology being so disruptive that it takes everyone a while to adjust. First, the welders are facing significant redundancies. And second, the contracting companies or the fabrication companies themselves may find their business models disrupted. But the two types of contract models on offer (recurring licence or unit sale) appear designed to ease the pain or allow a gradual shift if preferred. Nevertheless, having to retrain, retool and make some redundancies would mean that management are having to revisit some of their ways of doing things. Therefore, may take a while. Accordingly, however, it might be a long ride upwards. Perhaps a bit like when NC (numerically controlled) machine tools came to replace significant numbers of skilled machiners. And, similarly, there might be a bit of labour relations involved too. But, as always, DYOR.
