Economic models are bad at predicting the exact time of a recession, but basically all economist can agree that we will have a recession in the future. We had enough of them in the past.
However the point in the article is that we live on a planet with limited resources and resource consumption and the size of the economy are linked. So the idea is that we run out of resources. A good example of that is climate change. We have a limited somewhat save carbon budget and are on the edge of moving past it. This is why we see a massive heat wave in India right now, for example. That heat wave is really bad for the economy. This is one of the ways civilizations have collapsed in the past.
