It is funny to see how different people interpreted the original post.
For me it was about coding being a craft and not a necessary skill like arithmetics, reading or a secondary languages. (This is true not only for coding but for nearly every craft there is.)
So I think it was more a post against the "Every one should learn to code, for a better world" movement (if there is such a thing) than a keep on doing what you do and stay away from my craft post.
While I thing bloomberg should be able to do what ever he wants in his free time. I agree with the assessment that it will be highly unlikely that leaning to code will make a difference in his daily work.
So while this reaction was a entertaining read I think it was reacting to something that wasn't be said.
