When we arrive to the 2030’s, the life COULD change a lot, or maybe not much at all. For example, Republic of Turkey’s economy is falling rapidly, as well as the Syrian refugees entering the country every day. In the 2030’s, maybe the Syrian civil war can end and the Syrian refugees can go back. But maybe, WW3 could break out. The tough relations between Russia and USA, Turkey and Greece, India and Pakistan etc. could really lead to another huge world war. The nuclear war could break out, which could be the extinction of humans, or all of the Earth. Maybe the war wouldn’t break out, (delayed or fully abandoned) which could let all of the nations to improve themselves in terms of economy, population, income etc. Global warming and pollution can also start to get more dangerous for the Earth.
So, in short, the world could fully collapse; not leaving behind any sign of humanity. Or, the world could experience more scientific developments, and improve more in economy. Maybe I am wrong, but in my opinion, these are the things that will most likely happen in the future.
