I have a hard time believing that people use SD cards more frequently than they do USB-A. Sure, photographers probably get good use out of it, but developers, students, content creators who aren't shooting with DSLR, animators, musicians, 3D artists, regular artists and video editors will probably never touch it.

There are plenty of fairly common USB-A peripherals still in use anyways. A lot of audio interfaces, mice, keyboards and webcams rely on low-bandwidth but ubiquitous ports like USB-A. Apple and their pride would never put one on a modern Mac, but we're really at an impasse: neither side will adopt either standard, so it's more likely that we'll simply see wireless peripherals gain popularity instead. Not exactly bad, but kinda an asinine take for a company that just released a professional desktop computer with USB-A, but refused to add it to their laptops.
