The facet that is missing is the impact on users' code complexity. It is all well and good if Go is simple, but if my code is horrendously complex to compensate, it isn't a net win. I exaggerate, but a lot of the complaints for Go already stem from this trade-off. Focusing entirely on the language itself is a failure. Keep on eye on the language's users,
