While no one can truly predict future outcomes due to the simultaneous machinations of 7 billion different minds, we each probably have sense of when the stuff will hit the fan based on broader trends like climate change and technological developments.
I, for one, have been increasingly convinced that we'll have about ten relatively good years left, follwed by about ten very rough years and then perhaps full on global collapse or nuclear war. My thoughts are influenced by the MIT and NASA-related studies that suggest a likely collapse around 2030. That is a mere 16 years away, but I'm convinced that the personal and political feedback loops would begin well before that as governments and individuals see the writing on the wall and as societies feel the perpetual strain of warming, higher food prices, increased conflict and disease. These anxieties will make it hard for society to hang together and will cause governments to pursue more hostile agendas for resources. The idea of society and capitalism being fundamentally disrupted by automation also seems inevitable. Of course unforeseen calamities could knock us down before 2030, but what are other's thoughts on anticipating timelines for collapse?
