This was my take, too. I'm not overly worried--the company will be fine, and 2018 should prove a banner year overall. But the assurances of short-term 2,500 by end of March, 5,000 by end of June were very iffy. At one point Musk even mused about how they're taking all the learning from the problematic-to-manufacture 3 and applying them to the design of the Y. Which is nearly verbatim what we heard around a year ago, only with S/X learnings applied to the design of the 3. We had Elon forecasting 3-6 months at the outside for a coast-to-coast autonomous drive, released to customers by the end of that frame. Which is what we got 6ish months back. Didn't happen, and the timeline has shrunk by 0% since then. My Model 3 delivery estimate still says Dec-Feb, which is a thing that already has a zero percent chance of occurring. No discussion in the letter or call of customer impact of the next few months' ramp plans vis-a-vis prior/current estimates. And McNeil leaving, with no plans to hire anyone to handle sales/service other than the group reporting directly to Musk? Uhh.
Clearly this is difficult stuff, and I'm over-simplifying. My overall impression, though, is that we got a lot of discussion over what should happen / is expected to happen and very little we did what we said we would. Why would we take the musings over 600k 3s at Fremont seriously when expectations have been so seriously mismanaged thus far?
As a wise man once said, this was very much sizzle, very little steak.
They'll get there. I have little confidence they'll get there when they say they will. Which is pretty par for the course--but the 3, 'designed for simplified manufacturing' was supposed to be a turning point. Clearly it was not (or has not been in its first 6 months of production), and I have little faith it will turn into one in the near future.
