My career in high-temperature oxidation research began just about forty years ago, largely by accident. Interestingly, the first paper written on high-temperature oxidation was published forty years before that. It seems logical, therefore, to look at what the next phase of our subject might be. My career began when some major changes in the subject were taking place, in part because of the introduction of new techniques; but also because of a change in the way we thought about the issues. As I will show, another factor was a change in the temperature ranges for which structural materials were needed, and a significant change in the aggressiveness of the environments to which they were exposed. For the future, we need to ask to what extent these four factors appear to be changing now, and what new drivers we might predict.
