Is there any reason to believe it would be happening now if he didn't exist?
I am so amazed by the genius of making it out of steel. It's just so completely counter intuitive but has accelerated their progress so much. If they told you the stats of the material, better strength at cryo tempertures meaning mass reduction, higher melting point meaning minimal heat shielding and great thermal conductivity it would be easy to imagine it was some new super composite. Then your head explodes when t…

How come no one thought of using steel before?
380s for ISP for the Raptor vacuum engine seems durn good, considering the tradeoffs between hydrogen and methane. The most efficient engines we've flown, the RL-10 [0] (used on the Delta IV and Atlas rockets as part of the Centaur Upper Stage) and the RS-25 [1], (the Space Shuttle Main Engine) get around 450-460s for their specific impulse. These engines use liquid hydrogen and liquid oxygen. The issue with liquid h…
I suspect that Starship will fly to space before SLS ever will. I also think Starship has a significantly higher chance of flying at all than SLS.
FWIW SpaceX is exactly the kind of phenomenon that might spur state investment.
Eventually the shell will be a single large roll of steel that is unrolled, bent into a tube with a seam going hotdog that is welded. It will be very strong, lighter than the current patchwork, and extremely beautiful. More similar to the renderings. Can’t wait.
How do you picture them rolling a piece of steel 50 meters wide? As far as I know, the widest rolling mills in existence are 5 meters wide.

I'm surprised the guy being a youtuber. He is the codecs guy at Apple Computers
Eh, it's just another form of blog at this point. Not the greatest for searching, but a valid medium for expression.
I would not be at all surprised if there's a List Of Things Apple PR Hereby Politely Requests That Scott Doesn't Mention.
When I was at AWS I was similarly forbidden from mentioning anything to do with video games to just about anybody, despite not having anything to do with video games myself, and many other topics besides the obvious (e.g. "don't disclose EC2/S3 capacity numbers"[1], "don't reveal how Glacier works"[2]), and in fact there was a whole programme of PR training and tiered permission to speak at conferences or to the press/analysts that boiled down, mostly, to knowing what you could and couldn't say, and how diplomatically you parried questions on the latter.
Either that or Terry Pratchett's law of rewritten rules applies.

[2] it's a massively redundant array of vinyl records

https://youtu.be/Sdwy9fzQzl4 Scott Manley does a great job explaining such things!

Many jurisdictions would still have an issue with him using the title engineer. (edit: it's recently been determined to infringe on first amendment rights [3]. Still applies in Canada)
