We tend to forget when we live in a given age that industries come and industries go, relatively quickly. Coal is a good example in the recent energy industry. The rise of inland extraction makes offshore expensive. You only have to look at advances in windfarm technologies and the fact that car companies are now all moving to electric to realise that big changes are in hand. Drone technology advances don’t help the rotary industry from a pilots viewpoint and self driving cars aren’t that far away along with vastly reduced car ownership. I’m not suggesting it’s all over but I think it’s certainly a new norm rather than a dip.
