Tbh the keyboards at the time when the hamburger menu first showed up had symbols quite different from the symbol of the hamburger menu. And at the moment that symbol still looks different in the same way. Perhaps eventually keyboards will begin to use the hamburger menu symbol on the menu key. Probably a few do already. But I mean most keyboards. And also the hamburger menu symbol is not so much different from all of the other “mystery meatballs” (as Lynda Weinmann called them, many many years ago) that we all know and love. Today I expect that most people will be able to recognise and know how to use the hamburger menu.
