> the _actual_ question is more like: "Given the finite resources of the environment, human lifespans, available knowledge.. and so on..., at what point does economic and industrial growth in <_these specific ways_> stop adding to overall human happiness, utility and long term survival?"

Take out the industrial growth requirement and other crud and this question naturally simplifies to “given finite resources how can we keep increasing human happiness, utility and surivival?” And the answer is simple. Use fewer resources to create more happiness. Which we’re doing. Energy and material intensity of GDP is falling. We need it to fall faster. And we probably need more metrics. But fundamentally, the issue isn’t a problem of stupid people. It’s one of limited definitions of production, growth and what makes us happy.
