For the last 260 years or so we’ve behaved as if we live in a world of infinite physical resources. We don’t, obviously.
But that doesn’t necessarily mean a ‘no-growth’ future. It just means finding a different, less damaging kind of growth.
If the things people really want, beyond food, shelter and family are agency, mastery, autonomy, purpose and community – personal growth and development – then we will never run out of opportunities to grow these things, just as we will never run out of opportunities to ensure everyone is fed, sheltered and cared for properly.
Plenty of scope for human ingenuity I would have thought.
