Yes I agree with what you are saying looking strictly at my own experience as a candidate and as a hiring manager. There's nothing wrong to get slowly to the point where you can ask candidates about complex algos, it just allows you to see how far one candidate can go. The new trands are not supported only buy young people that jump from trand to trand. That was a terrible thought, maybe showing some frustrations?... But I have to agree with the author, many times we have the tendency to overcomplicate a solution for the problem at hand. To keep it simple and stupid and smart it is close to an art. Especially when there pressure to get things done quickly and you havd to keep on improving an existing solution. Lots of levels touched by the ideas in this article.
