In Electronics world? Bipolar junctionTransistors. Easily.
This led into having portable devices we have today.
Back then people used vacuum tubes for switching and amplification; of which were very expensive to run (used a lot of power when idle).
I mean, vacuum tubes where phenomenal when they came, allowed first long distance calls in 1915, but look at my phone now, fits on my hands, and has billions of transistors!

Its crazy that we’re now approaching 200 million transistors in a single square millimetre. Boggles the mind.
