3 . By mid-century there will likely be 9 billion people on the planet, using ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence (AI) advance? Will global warming cause disastrous changes, or will we be able to engineer our way out of the climate change issues? Recently, the magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is as follows.
It's likely that by 2050 the majority of the people in the world will live in urban areas and will have a much higher average age than people today. Cities theorist Richard thinks urbanization will transform the education system of, making our economy less houses driven and removing the divisions between home and work.
And rapidly advancing technology will continue ever more rapidly. Cities of the future won't look like “some sort of science-fiction fantasy”, but it's likely that technological advances and information overlays (VR and AR) will greatly change how we live. Self- driving cars will make the roads safer and provide faster transports. A larger version of driverless cars-driverless trucks — may make long-distance drivers out of date.
Some long view predictions are completely dire. Environmentalist Bill says that if we don't make great progress in fighting global warming, it's likely we could see out-of- control rises in sea levels, huge crop shortfalls and wars over limited freshwater resources.
In terms of how we will eat, green markets founder and “real food" supporter Nina believes that there will be more small milk processing plants and more regional food operations and we'll be healthier as a result. New York Times writer Mark thinks that people will eat fewer processed foods and eat foods grown closer to where they live. And more people will be aware of the ethical responsibility" to grow foods.
