Some keyboards and operating systems — iOS is one of them — convert two dashes into an emdash.

And macOS, at least my keyboard layout, has both en and em dashes easily typeable with Alt+- and Alt+Shift+- respectively.

I use emdashes and endashes all the time—but maybe that's because I'm an academic?

I use them – well, mostly en dashes because that's the custom where I'm from – because I'm a bit of a typography nerd and have grown to dislike the barrenness of ASCII.

I can’t wait for my keyboard to start auto-completing “Your” with “are absolutely right!”

In this case Apple has cared about typography since its very beginning. Steve Jobs obsessed over it. The OS also replaces simple quotes with fancier ones.

I do the same on my websites. It's embedded into my static site generator.

Agreed that is useful, despite the unintended consequences of dash meddling.
