Helvetica, which was replaced by San Francisco fonts, was created in Switzerland in 1957, when there were no digital devices. Helvetica is widely used by many companies as the corporate type even now, and no doubt it will be used for the future as a great classic font.
San Francisco, on the other hand, is a modern font. It will change the typefaces dynamically according to the context. It is a kind of “Digital Native” fonts for the digital age.
