Boom and bust cycle? There’s been one boom and now there will be one bust. Unless you have some fancypants geoengineering idea which will stabilize the climate and put fossils back in the ground.
There've been plenty of booms and busts before, eg. the late Bronze Age collapse, the fall of the Roman Empire, most Chinese dynastic transitions, the destruction of North American civilizations by colonialism. This boom just happens to be bigger than the ones that came before.
