Given that we're already 5+ years into Apple's USB-C revolution, I'm not so confident that this is going to happen. I'm going to keep using my USB-A peripherals for a long time, and more importantly, mice, yubikeys, keyboards, and a whole lot of other things are still largely sold with USB-A. Some of those have replaceable cables... but it's still a lot of effort to move away from that.

Furthermore, ditching all of those USB-A accessories and cables that still work fine just feels wasteful. If the only thing you're throwing them away for is compatibility, and not some feature that's actually improving them, even more of a waste. It's just churn to push more tech company profits.

This is a gradual transition. Most electronics last somewhere around 5-8 years, so we're looking at another 5 years before we can truly ditch USB-A.

The fundamental mistake Apple made was continuing to ship USB-A cables in the box with products, and expecting USB-C adopters to pay up for USB-C cables. This was good for Apple's short-term margins, but terrible for the transition.

So, I blame Apple for keeping USB-A alive. They introduced the all USB-C Macbook Pros in late 2016. You'd have expected that over the next year they'd have phased out USB-A, so by 2017 or 2018 they'd have not shipped any USB-A cables or adapters in the box.

But nope. Airpods 2 (released in 2019) still ship with a USB-A cable in the box. It's the same with the iPhone 11 (2019), and the Magic accessories for MacBooks until 2021.

Interestingly, this is also a good argument for why the EU shouldn't force iPhones to use USB-C. People have tons of lightning cables that would become e-waste overnight, and all the demand for USB-C to USB-C charging cables would be profits of (some) company - Apple, Anker, or random Amazon companies.

I remember hearing someone point out during that period that if you bought an iPhone and a MacBook, brand new, you couldn't plug the phone into the computer out of the box. Which seems like one of those things that would have been unacceptable to Jobs if he were still around.

USB-A also became so widespread that they became wall plugs in their own right, so at least those will stick around a lot longer unless people start hiring electricians to change their plugs.

USB-A is alright for charging small electronics. It's 5V and somewhere between 0.5A and 2.1A (1A is very common).

I have charging cables (with USB-A on the power side) in multiple places around the house, using the 5V/1A adapters that shipped with iPhones over the years. This works fine, though it is slower than the "fast charging" we've grown to expect these days.

The device end of these cables are miniUSB (bicycle lights), microUSB (external battery pack), USB-C (my partner's noise cancelling headphones), and many of them are Lightning (Airpods, Airpods Max, iPhones, iPads, Apple TV Remote).

I suspect USBA isn't going away, it's far more robust than USBC, what I suspect will happen is devices that need smaller sockets will use USBC and everything else will stick with USBA. There is a reason I have one USBC port on my motherboard and 5 USBA ports.

Guess I'm the opposite. I hate USB-A the connector with passion. I always have to try 2-3 times to be able to plug the USB-A connector in. Now I keep only 2 USB-A chargers in my home for legacy devices and advice my wife explitcitly not to buy new gadgets with USB-A connector, be it mini or micro.

Here's a slightly helpful tip. USB-A connectors have a USB logo on them. Look at or feel for that logo on the connector and always have it face up when you plug it in. It should always work.

There's a few exceptions. If the USB-A jack is rotated sideways on the device, then "up" could be left or right. And if it's a cheap off-brand sweat shop connector, then the logo may be on the opposite side. A sign that it could break quickly too.

I've marked the top of all of my USB cables with contrasting paint.

At some point in the future, USB-A will be phased out. If only because new devices will need the better profiles USB-C provides or because enough devices will no longer support USB-A.

I'd say 3 more years will be the turning point. You must remember, before USB there was no universal port. So USB-A didn't have to replace it's predecessor.
