In the next 50 years or so, it's hard not to see a world populated with a mixed race of people, with most people

Having some amount of Indian or Chinese in them. Indians and Chinese make up 2.74 bn of 7.8 bn people in the world. The level of competition in these two countries as a result of their population, in business, education, sports, or pretty much anything make it impossible for anyone but the very apex predators at the top of their careers to thrive. It's only logical that citizens will look to move out of their respective countries in search of better opportunities and more importantly, wages relative to their labour. India's resources will be unable to support its ridiculous population. At the same time, liberal governments quite possible will increasingly welcome two of the most intelligent races in the world.
Other developing countries like Vietnam, Myanmar, Nepal, Sri Lanka will experience similar changes. As will several African countries.

With national borders becoming increasingly indefinite, it's hard not to see a mixed race in the next 50-70 years.
