It’s glass - it’a not pixie dust doped adamantium.

Metals arent particularly strong. Glass, plastics, etc are all stronger (yield strength). But boy are they ductile, and very tough. Iron can take, literally, an infinite number of loading cycle.

You can make ceramics, glass, etc better but the overall performance package of iron is very hard to beat.

If I were to dismiss SpaceX as 1950s technology with modern electronics and engine technology the soviets mastered in the 60s would you be annoyed?

So why dismiss the truck manufacturing industry? Semis are very thought out solutions for their domain.

My problem was comparing the iphone that has a $1,000 price point to the new glass of the semi. I'm not comparing anything to truck manufacturing industry. I presume that that it also costs more than an iPhone. So what's your point?
