Extrapolating the future from the present is completely sensible. Today's society is not that unthinkable for somebody from the early 20th, or even 19th century: People work jobs in offices and factories; they complain that they're busy. Health, transportation and communication have improved. Poor people fight and die in wars that rich people start. My prediction for the rest of this century is that all the large scale trends will continue. There will be no sharp discontinuity with the past. Renewable energy use will increase, and climate change will keep getting worse. More and more species will go extinct. Computers and batteries will keep improving at a decreasing rate. Robots will not take all the jobs. Poor people will continue dying for rich people's mistakes.
