The so‐called ‘flat optics’ that shape the amplitude and phase of light with high spatial resolution are presently receiving considerable attention. Numerous journal publications seemingly offer hope for great promises for ultra‐flat metalenses with high efficiency, high numerical aperture, broadband operation… We temperate the expectation by referring to the current status of metalenses against their historical background, assessing the technical and scientific challenges recently solved and critically identifying those that still stand in the way.

• Dimerized high contrast gratings (2018, background): “Recently, a class of flat optical devices called metasurfaces (and, in particular, metasurface lenses [16]) has been of interest in controlling both the phase and phase dispersion of the output wavefront [17–20].”
