These are all great questions. I'm super curious to see if any or all will be answered.
When you said:
There are going to be a ton of naysayers regarding Tesla expressing doubt and skepticism. It is amazing how so many think they are smarter than Musk and know better than he does.
I honestly do think it's both valid and justified to be skeptical of the things Musk says.
Look at this:
Model Y price will go up by $1000 in April...
Instead of the price actually going up, the price came down.
Did Elon knowingly lie? Did Elon make a mistake? Did Tesla have to change their minds? Who knows... it doesn't really matter.
I seriously think it's wise to have some skepticism with announcements from Tesla and Elon. I don't at all think I'm smarter than him or know better... but he's famously inaccurate.
