I don't care about growth, nor do most people I know. We don't need to endlessly consume to be happy. The world won't end when this economic system unravels either, it's not the first and it won't be the last one to fail.
It was massive turmoil for sure, but world didn’t end (I’m referencing your earlier comment, not downplaying the devastating fall).
How would continual growth work? We will run out of everything.
Continual growth is possible in at least two ways:
1) standard sigmoids, which never stop growing yet are also finite
2) standard ecological growth, where growth is never ending but so is death. This is much more typical of systems like capitalism than sigmoids growth. New upstarts experience exponential growth for a whole, then peak, and then die.
Of course be careful of mentioning these standard scientific observations around those in the degrowth cult, as the cognitive dissonance may cause an unpleasant explosion.
