  Growth rate of the world Growth Domestic Product (GDP) is analysed to
determine possible pathways of the future economic growth. The analysis is
based on using the latest data of the World Bank and it reveals that the growth
rate between 1960 and 2014 was following a trajectory approaching
asymptotically a constant value. The most likely prediction is that the world
economic growth will continue to increase exponentially and that it will become
unsustainable possibly even during the current century. A more optimistic but
less realistic prediction is based on the assumption that the growth rate will
start to decrease linearly. In this case, the world economic growth is
predicted to reach a maximum, if the growth rate is going to decrease linearly
with time, or to follow a logistic trajectory, if the growth rate is going to
decrease linearly with the size of the world GDP.
