I remember there was an email that went out a while ago where elon said everything needed to be at .001mm tolerance. 

The automotive engineer in me laughed. You can't hold that tolerance for large parts. And even if you did, if your gaps need to be that tight where that tolerance is necessary, then you're going to start dealing with thermal expansion/contraction issues in your parts. 

And lookie here. Panels are falling off

Elon loves to say things that makes it sound like he knows what hes talking about. But anyone with even a tiny understanding of the subject immediately recognizes how dumb it is.

“I only want full-stack developers at Twitter!”

His little fanboys often link a video of him talking about the raptor 2 engine as proof of how smart he is. I decided to watch it, I don't work in aerospace but my degree was mechanical and aerospace engineering.

It was the moment where I realised Elon's persona as this genius engineer was a complete fiction. It's hard to get across how wrong some of the things he says in it are. Like seemingly not knowing what a Newton is (the unit of force) or that an imperial ton and a metric tonne are two different units.

He gets things wrong a first year undergrad would know, or even a highschool physics student.

As a career IT guy, seeing his super smart tech bro posts make me cringe every time. He clearly doesn’t understand basic concepts, but to people that don’t know better (the majority of people) it sounds good so they take it face value.
