OK, after sleeping on it... Only issue I see is that, with a few notable exceptions, we're an overly-optimistic bunch in this thread, so any further delay hurts. Overall though, I don't see any fundamental change.
I was initially dismayed but the 10% reduction in MS/X build capacity, but the rationale behind it seems sound.
Only regret is that I don't have any cash to buy some more
EDIT: I was a software developer for much of my career and when asked for an estimation of how long to deliver a piece of code I would always give an optimistic response, which was accurate if the code worked pretty much first time, but in reality it's never like that. After some years of constantly getting burned I learned to double my initial estimate, then double again, which then became uncannily accurate, so that's my advice to Elon at this point
