Ask yourself what the real subtext is; what most people are going to think when they read "But actually almost all my time, like 80% of it, is spent on engineering and design".

Is the mental image that of Tony Stark, single-handedly designing rocket components in some kind of advanced cad/cam-ish lab, scoffing at staid business meetings he delegates, or is it of a guy talking to a bunch of engineers, and hearing presentations, picking favorites among a bunch of proposals, signing off on this or that?

You are supposed to think of the former (PR), whereas the latter is closer to the truth.

Yeah, I imagine the latter is closer to the truth. I doubt Elon is spending all his time in CAD software, but I'm pretty sure he talks to people who do and looks at their work, and can meaningfully comment / advise on it.

I've seen the type before. I've personally met one of the guys running Reaction Engines Limited (the Skylon company); I've been on a talk he had for physicists at Rutherfort Appleton Laboratories. He mostly talked big-picture things during the presentation; then on a Q&A session someone asked him about details about the engine, and the guy went into full physics professor mode, explaining the engineering tradeoffs they made in excruciating details.

That's how I imagine Elon too.
