> Type-A has completely disappeared from my life and that of my family's.
I'm honestly surprised by this. I have eight different type A devices plugged into my PC right now[1] and I don't own a single type C device (and it's not that I've intentionally avoided it).
As for the rest of my family, I don't think any of them have computers that'd even have a Type C port. Mine has just one, and it's brand new.
Those mostly aren't "type-A devices". The connector is not the protocol. Except for those physically integrated into a type-A connector, those are mostly USB-2/3 devices that generally ship by default with a cable that includes a type-A connector at one end and a type-B or mini/micro-B at the other.
I too have an external audio interface, a printer, scanner, and external HDD, and they are all connected via USB cables that have a type-C connector at one end and the relevant B subtype at the other. These are now cheap and ubiquitous. My keyboard is lightning to USB-C, and my mouse is bluetooth. As for flash drives, I buy the double-ended ones these days.
The adapters I still use are for an older U2F dongle that is physically integrated into a type-A connector, which is due for retirement later this year, and a Thunderbolt display.
So the writing isn't just on the wall for USB Type-A connectors in my household, they're basically gone.
As for what happens to all the cables with type-A connectors that shipped by default, those are in my travel kit for device charging off wall-warts or vehicles that often still have type-A sockets.

6. Wi-Fi adapter
7. Xbox 360 controller
Now that is my desktop, my laptop is USB-C, with a dock plugged into the port. Said dock only has 2 USB devices plugged in, wireless adapter for my Mouse/Keyboard, and my headset.
None of this counts the many USB-A charging cables. I have USB-A to Lightning, USB-A to Micro, and USB-A to USB-C, all currently in use. I also have a single USB-C to USB-C adapter.

Edit: Valid point made in the replies that 50% of these could have their cables replaced to do USB-C at one end.
Cable could be replaced: External audio interface, printer, scanner, External HDD.
Cable not replaceable: Keyboard, mouse, iLok dongle, flash drive.
