I can say that I have experienced firsthand at least 4 important global “revolutions” of this industry, plus some intermediate upheavals of lesser impact, which, over the last 40 years or so, radically shaked the foundations of its methods, hardware and software systems, costs, technologies and manufacturing processes.

That is: why at a certain point in our lives did we decide to practice this profession, precisely this one, and not any other?
What drove us to make this job our life?
