I would bet that this is not going to happen unless someone finds an industrial use for all that carbon. I’m not an expert but it seems like it would be much more efficient to invest in low carbon energy and manufacturing tech than to build a ton of infrastructure for sequestration.

The issue is that some things are difficult to decarbonize because they emit carbon directly due to chemical processes or use gas for process heat. There is a lot of investigation into whether these can be decarbonized economically, but a lot of it is still fairly early stages. It makes sense to have a variety of solutions available, especially for the short term.

If the story of Earth were a novel and the current chapter introduced both global warming and the advent of carbon-based manufacturing, it would almost feel too contrived of a setup.
