Iain MacLeod's discussion (Letters 14 April) reminds me that the word 'engineer' derives from 'ingenium' (the same Latin source as 'ingenious'). An engineer is not simply a processor of data (else we would surely be called calculateers) but someone who is skilful in combining ideas.
That demands a thorough mix of learning, practical training and innate talent. Non computor sum!
