I'm thinking about a line from an older movie.

"The Graduate."

At a party, Dustin Hoffmann is given some advice by a business type.

He's told, "Plastics."

That line reflects how we looked at plastic back then.
Cheap, was thought of as a crass imitation of "real" stuff.

Nowadays we are arguing about working plastic guns.

And many of us literally would be dead now without plastic.
