Fabrications of these meta-lenses should also be much more cost-effective, compatible with silicon chip technology versus complex polishing and sometimes stringent requirements for high-performance lenses.
Technological innovations such as the water wheel, the plow, the steam engine, electricity or the silicon chip can make a tremendous difference in whether work will be enjoyable or not.
Intagliata: Still, they all pointed out that silicon chips first reached this level of complexity a long time ago—in the 70s and 80s—and had to overcome many similar challenges to get where they are today.
