He's a fictional conversation [1] between an economist and physicist where they discuss this very premise:
Economist: Hi Tom, I’m [ahem..cough]. I’m an economist.
Physicist: Hey, that’s great. I’ve been thinking a bit about growth and want to run an idea by you. I claim that economic growth cannot continue indefinitely.
Economist: [chokes on bread crumb] Did I hear you right? Did you say that growth can not continue forever?
Physicist: That’s right. I think physical limits assert themselves.
That article ties growth to consumption, and consumption to energy use. This does not have to be true.
We could all decide to multiply every currency with 10x and nothing would change except the number and we would have 10x economic growth as measured in the currency.
That is an obviously simplified example, but it is not that contrived. Modern money is not tied to energy use. Money is created out of thin air every day and that is ok.
It will still be anchored in reality, it just won’t have the guaranteed bump from population increase. Growth will be slower, but will still happen due to technology and efficiency improvements.
Once we set our expectations to 1% growth, there’s no reason that has to be a problem.
Economics is fundamentally about the allocation of scarce resources. So if we are talking about how human civilization allocates scarce resources (and not about some virtual economy e.g. inside a computer game), then economic growth is very much anchored in reality.
If it is not anchored in reality then you don't need growth how long until people understand that? You don't need to wait for economic growth in the opensource space. You just go ahead and download the software, use it and be happy today.
