It's best to review Musk's goals over the longest term possible, because who cares about being late for a few of the objectives if they are widely exceeded soon after the deadline?
I invite you to re-read the early presentations for the Model S and Gigafactory. Question: of the goals that have been achieved and those who haven't, which are the most important? And for the less important, are these delays interfering with Tesla's mission or just a temporary postponement to further focus on things that matter (e.g displacing oil and disrupting fossil fuel investment plans)?
