Academic arrogance may assume that solid research progress lures companies into the field, which may be driven to protect their pre-existing business based on lead-containing piezoceramics or because excellent, transferable expertise may enable new product lines challenging existing state-of-the-art technologies. In this latter case, however, several companies, like Toyota and Murata, e.g., Ref. 81, have been active in this field since the late 90s. Their expertise, in combination with new research funding in dynamic geographic areas and a newly created human potential eager to work in a field made attractive by its inherent nature of social responsibility, will determine the “slope of enlightenment”. If this picture holds true a plateau of productivity may be reached (in our prediction) between 2020 and 2025. Then, finally, the last sentence in the paper by Cross may come true: “As the results (referring to Ref. 1) are brought to the market place, all producers may be forced to explore this option”.We need to critically examine in the next sections if this promise has potential to hold true and which applications are concerned as well as which applications are not ready and should not be currently required to go lead-free.
