There is absolutely
zero need for USB-A. None. It does nothing whatsoever that USB-C can't do, and there are
ton of things that USB-C can do better. There is no need for two USB "mid sized" plug standards - and obviously USB-C is now the dominant. Almost every single peripheral, device, component, that can run on USB-A runs on USB-C. And there is a huge contingent of devices that could never run on USB-A. As soon as everyone has agreed that USB-A is dead, completely dead, people will cease manufacturing USB-A peripherals, which
further enhances the value of a port that almost everyone is now using for everything.
Honestly - the USB-A port should have been wiped out a couple years ago - the only reason it didn't is that everyone has this massive legacy of USB-A ports (Hotels, Airports, Airplanes, etc...) that people plug into, which kept them holding onto those legacy peripherals longer than they should have. Also - some weird hardware dongles that haven't been upgraded to USB-C.
What we need to do is start seeing how quickly Hotels/Cars/Airplanes/Airports/... start switching over to USB-C. When that happens there will be this massive cascade effect - it will be exponential:
2022 - ~0% of legacy is USB C
2023 - 1% legacy USB-C
2024 - 2% legacy USB-C
2025 - 4% legacy USB-C
2026 - 8% legacy USB-C
2027 - 16% legacy USB-C
2028 - 32% legacy USB-C
2029 - 64% legacy USB-C
2030 - 90% legacy USB-C
2031 - 95% legacy USB-C
I'm guessing by 2032, nobody will be carrying legacy USB-A peripherals anymore. Only wildcard will be if there is a USB-next that will replace C. Please don't let that happen before USB-C takes over the world.
