In order to have any level of technological sophistication, you must have a surplus to support specialization. In order to have a surplus you must have agriculture. Ethnic somalis were pastoralists thus no surplus to support technological advancement. Complex politics emerge from the need for a system of managing said surplus, if you have no surplus you have no Athenian democracy or philosophy. Civilization cannot emerge from a pastoral culture nor from a hunter/gatherer culture, it is not even assured when you have agriculture.
