<p>I edited the question and wrote that I want to delete it because of all the shitstorm and those who want can save the answers before they are gone. But my edit was denied. </p>

<p>Anyway, cynical answers to</p>

<p>What do you consider a person MUST know about statistics and machine learning?</p>

<blockquote>
  <p>Nothing. There is no must-know knowledge for 'a person'.</p>
  
  <p>Many people are living happy lives without knowing anything about
  statistics and/or machine learning.</p>
</blockquote>

<p>don't help anyone. I am surprised how little constructive users with this much rep can be. Instead of improving the question or asking someone else to improve it after saying what should be improved he decided to point out such problems in a completely useless and cynical and thus offending answer. Although he denied in the comments beneath his answer that the intent of the post was to point out how bad my question was he wrote here "I have added an answer to your question that may prove my point about the subjectivity and fuzziness of your question. It is too much unclear what goal should be".</p>

<p>Ironically, the question itself was not the problem and led to little discussion if you read the comments on the answers. But so did the whole "it must be closed because subjective thing lead to endless discussions" comments that started a huge discussion.</p>

<p>Anyway, after just seeing that this childish behavior got even positive feedback I delete the whole question. That is too much madness for me.</p>
