Better than even odds that in 2020:
GDP per capita at purchasing power parity for Singapore will be more than US$80,000 in 2008 dollars.
GDP per capita for China (PRC), will be more than twice 2009 GDP
Tourism to suborbital space will cost less than $50000.
Unless I'm missing something, looks like #1 is actually correct... 2019 GDP PPP per capita for Singapore was 103,181 according to IMF, which adjusts to 84775.10 according to the first inflation calculator on Google.
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
