It has, the only obscuring factor is China's one-child-policy and Europe's and North America's decline. The rest is still very much in exponential growth. Only the last 20 years at best saw some possible downward trend, but there have been similar variations before. So that's like reading the climate from small changes in weather, a fool's errand. Until there is a firm trend for a shrinking or stagnating population, all the small variations just lead to wishful thinking like yours. You cannot just ignore math and biology, populations will grow exponentially until they hit a limit.
