Algorithms, and the insight afforded by their formal study, are widely useful. In particular, algorithms are the core of CS once one abstracts the messier details of interface and low-level implementation. Therefore, algorithms are more suitable to formal analysis than any superset of CS, while remaining sufficiently general that observations about algorithms are insightful into the whole.
Trust the economist to produce a theoretical objection to a common practice despite the lack of actual problems observed.
No questions.
Perhaps I underestimate the background knowledge that can be expected, but I would think that it might be advantageous to start with a brief definition of an algorithm–this section seems aimed at those who know what algorithms are but are not convinced of their usefulness, which must be a rather small part of the population. Overall I would give readability 7/10; the lack of introduction hurts, but otherwise I thought it as well-written as one can expect for a section nearly without content by design.
