We are slowly getting there.
Very high end devices might have more than a single USB-C port (which is probably your case, given the "extreme" in the name), and these ports might even be Thunderbolt or USB4, but that's still rare. In my opinion, we are still in the USB-C equivalent of the "only two USB 2 ports, if you want more get a PCI add-on card" phase we had in the serial/parallel/PS2 to USB migration back in the day.
my current wireless mouse/wired keyboard have usb-c on the peripheral end but I still use usb-a to connect them to the computer
Ex. From my comment, GP is the comment by pynappo, starting with "i think the GP was talking... "
Similarly, you can have GGP for great-grand parent, etc.
OP refers either to the starter of the post or the top level comment.
USB-C erased that distinction in favor of a full duplex network connection between two hosts.
And USB-C is neither full-duplex (at least not for USB 2) nor host-to-host; there is a protocol negotiation and some devices can never act as hosts, although some can indeed assume both host and device roles.
Even in a “host-to-host connection”, only one side will act as the host.
In the same sense that A and B are variants of each other, sure.
Even though it's called micro-B, the design is closer to A, and micro supports both ends with basically the same plug. I would never refer to it as just "B". "B" means the square plug.
I wasn't being pedantic though. USB-B is in my experience used to refer to the square plug (commonly found in printers). Micro-USB seemed like a closer approximation to what I though that poster was referring to.
