There really are limits to growth and they trace primarily to government growth and growth of market warping regulation and taxation, to control by political actors who deny the laws of economics. In an actual free market economy there will always be innovation that will substitute for and replace declining or failing structures and resources. Rulers prefer that there be nothing new and that they control all that is. New things may be out of their control so must be prevented.

There's about 7 billion on the earth today. 1 billion in the Americas. 1 billion in Europe and Russia. 1 billion in Africa. 4 billion in Asia.

By 2050, Africa will add a 2nd billion and Asia will add a 5th billion. Total 9 billion

By 2100, Africa will add a 3rd and 4th billion. Total 11 billion

The article may have an element of truth mixed with an incorrect assignment of causation.

The article states that growth is being limited by hidden costs, i.e., the increased costs of obtaining energy and metals from poorer ores.

Note that there is no mention of the not so hidden growth of the US FedGov share of the GDP from 18% to 25%. That money is not available for either investment or for increased wages, and so it acts as a brake on economic growth.
