What people forget is that new hardware technologies can take decades before they are used in commercial products. Quantum Dots were first synthesized in 1981 and are only in commercial stuff since the 2010th.
Teflon: Invented in 1938- first commercial use in 1961.
Semiconductors: Found in 1898, first commercial uses in 1958.
- arijun 2y agoInteresting! TLDR is that Apple replaced a stack of four optical components with one flat metasurface to collimate the dots the FaceID camera uses to track face shape. Although they found it in the iPad and are only assuming (rightly, probably) that it will be in the iPhone 17. I wonder why none of the large tech blogs seemed to have picked that up?
