If you aren't you'll enjoy his latest novel "Ministry for the Future", which follows the line you describe and posits a post-apocalyptic future with less machine labour and more manual labour, abandonment of air travel, no meat consumption by humans, a solar array covering much of India, etc. He then proposes replacing Proof of Work with Proof of Carbon Sequestration. --- Aside: MftF is, to me, an appalling unscientific low effort bit of propaganda (at least for the first 60 chapters) but perhaps there is a way to steelman KSR's theses.
