[quote=pri_dk]Exponential growth simply requires that every year we find ways to do and have the things we want cheaper/better/faster/whatever.
0.001% growth every year is still “exponential.”
Most people don’t know understand what the word means.
Do you really think that we will ever run out of ways to do things better?
Is human ambition and resourcefulness just going to halt one day?
Why do so many present the question as a (false) choice: exponential growth or collapse?
Exponential growth isn’t that hard, and it isn’t that outrageous.
In fact, it’s all we have ever known.[/quote]
Growth requires that the total amount of money that we spend increases.
Yes, we will continue to do things cheaper/better/faster. But when things get cheaper, growth goes down. Better and faster do not necessarily translate into economic growth. Most electronics have become cheaper over the last 30 years. Also, information will continue to be cheaper. Especially when the copyright/patent expires. The goods that become more expensive are primarily resources that are not unlimited. Land, oil, metals, food.
