So, you (a regular private pilot) go up in a 172 with a friend who is
not a pilot, you let him take the controls while you very carefully
supervise her, and you can't log the time PIC.

That's right. Not only that, but you've probably broken FAR 91.13 by
letting a person without a valid pilot certificate fly the plane. (A
little discretion goes a long way in such situations.)

The next day you fly a
Cirrus by programming the CID (Cirrus Autoflight Device) and pushing the
GO button, essentially become a passenger while the glass cockpit does
the work, and all that time goes in your book as PIC.

That's right, because you're still responsible if the CID goes belly-up.
That (and FAR 91.13) is why you can't just take a nap even when the
autopilot is on.
