Regarding technology taking time: look at LEDs.
- The effect first discovered: 1907.
- First prototype device built: 1927.
- First commercially viable parts shipping: early 1960s.
- Ubiquitous and cheap as an indicator device: 1980s.
- Highly efficient, used for lighting: 2010s.
The principle never changed along the way. The specific materials changed quite a bit.
