Stone Age

Bronze Age

Iron Age

I would add Steel Age here

LK-99 Age

Given that human flight and putting things in space rely on Aluminium, I think that's worth a mention too.

And the beverage can! While it seems mundane it's extremely effective at what it does and it's actually recyclable (unlike most things).

I think a silicon age would be appropriate too.

I was thinking steel reinforced concrete but yeah Aluminium or Silicon would fit here also.

And Silicon after Steel

Do not forget the Carbon Fiber age.

Silicon?

Don't forget the plastics age...

Okay, I think I've got it.

Stone Age

Bronze Age

Iron Age

Steel Age (1800 - 1940. The development of mass-produced steel of high quality, and its widespread adoption and use in construction and by industry.)

Aluminum Age (1940 - 1965. Tremendous growth in the aeronautical and space industries, enabled by the futuristic light alloy.)

Plastics Age (1965 - 1985. Ubiquitization of lightweight, durable plastics in all forms of consumer goods and media. The M-16 "plastic rifle" and the polycarbonate compact disc are symbolic of this era.)

Silicon Age (1985 - 2023. The age of computers in everything, the internet, "smart" devices, gig economy, etc.)

LK-99 Age (2023 - ??. Could end next week, could last a while. Nobody knows.)

No silicon age and plastics age?
