Nothing will change significantly over the next 50 years, despite people constantly predicting otherwise.

My personal take is that we've reached peak humanity. Without some large shock to the global eco-system there will be no significant progress in anything meaningful. The 20th century only resulted in major advances in many fields of research due to two world wars. War is the driver for change.

If you want a better human race, have another war.
