I'd definitely argue that no language ever will "feel natural" unless it fundamentally changes the metaphors of computation. Humans just don't think in sufficiently "hard-boundary" terms for programming as currently phrased to come naturally. Granted, culture has made up for a lot of that - in the UK, children are expected to be able to perform arithmetic, which presumably helps a lot in instilling the appropriate style of yes-no exact thinking - but I don't think the programming mindset aligns well at all to what was in the ancestral environment. Our minds are classifying machines built to do Just Well Enough in a world where everything is shades of grey; programming is the art of making the world concretely align to a well-specified model.
