Thoughts On Organic Webbing?

[CosmiComic]

The AI, the tracers, all the webbing combinations, the Iron Spider, etc. All of those are things he should have created himself.

I'd agree with the other stuff, but how would Spider-Man create the Iron Spider suit? Tony gave it to him in the comics too

I'm speaking about his engineering/chemistry "background" more specifically, and how Peter never seems to grow or utilize that side of his persona.

Yeah, he could use his knowledge to create inventions which might actually help fellow working-class people, if that's such a major facet of Peter Parker's character
