@swenani, the possibility of machines surpassing human intelligence is covered in the idea of 'technological singularity' take a look

We also need to remember how intelligence is developed in humans. Intelligence is developed through symbolic manipulation, scenario planning and simulation, experimentation, communication and social organization, and health optimization. Then through time intelligence increases. For example, Australian aborigines had/have a concept of 'dream time'. Nowadays quantum physics has parallels to this system.
Given that machines are capable of 'evolutionary leaps' in such a short time, are less susceptible to human weaknesses like hunger and fatigue, then they should be able in time to even program themselves. You may need to watch the documentary on the 'deep blue' beating Kasparov in chess to get a feel of this.
@Obi raises an important point and it's a crucial factor in the development of a strong army; the ability to link defense activity to the economy to enable increasing returns like the 'military - industrial complex'. So far, few countries can afford such systems (Militant groups are more vibrant here) and Kenya isn't one of them. There's no market control and that's a great weakness. There's a need for better economic systems.
