I think in 2050 year humanity become more well developed in many techs,

starting out from mechanical engineering and ending space technologies.

humanity will definitely feel big technology leap, will invent rocket that can reach Mars, maybe will invent the cure from the cancer, the new viruses will apear, you can't say for sure what can happen in 2050 year, because almost year something happening in world what no one expected. Of course i dont think what humanity will invent flying cars or etc. from science fiction it will maybe apear in 2100 - 2200 yy.. We Сan not exactly say what can happen in 2050 year, maybe generally humanity will die from asteroid or something like this. No one know. undoubtedly world will undergo changes.
