This is an industry that has had 15-20% returns for decades. I'm not sure what "computer sciences" is as an industry separate from the rest of software, but saying there are some sectors more profitable than pharma says not much. Pharma is huge as a fraction of GDP and consistently profitable because its profit is based on rents. If it is flagging in recent years it is because public sector spending on research is flagging and hasn't yielded as many cash cows as usual.
