"Well, on the Brasilia..."
This is the only memory item that matters.
(Slight exaggeration, but you get the point. Breathe. Fly airplane.)

Awful accident, and partially down to the crew's failure to identify the cabin altitude warning as in different conditions it was the T/O Config warning (other factors include poor checklist discipline, the Captain's poor CRM and tech knowledge, and poor language skills amongst the crew). I believe the Boeing legal team didn't allow them to change it after the accident as it would be seen as an admission of fault in the litigation. The pressurisation system in the 737 is full of ways to accidentally asphyxiate yourself.

I can't speak for the Gulfstream but the EASy2 upgrade for the Falcon has an Automatic Descent Mode option (ADM). The airplanes I fly don't have it due to some other limitations but I do remember in ground school them talking about it. It will make a 90 degree left turn and begin a descent to 15,000.
Here is a link with all of the details.

This is why I keep the cabin altitude gauge a part of my scan when I'm at altitude or climbing to altitude.

It should be part of a regular operational check, just like the engines, fuel, and other basic core things you check every five or 10 minutes in flight.

I can only speak for the G450/550, but it has a similar thing to the Falcon mentioned above.
It is Emergency Descent Mode (EDM) and if above FL 400, with the autopilot engaged, it will activate the auto throttles if not engaged, bring power to idle, descend at MMO/VMO down to 15,000', and execute a left turn of 90 degrees. Hopefully, you wake up before you hit the Swiss Alps.

Why does it turn left?

Ain't nobody got time for that
Maybe to signify to ATC that something isn't right.

The X had EDM as well but it was particularly useless without auto throttles. I keep my eye on the cabin PSI gauge. I agree with @Hacker15e on it's importance. Although to be honest I'm not checking it as often as he recommends.

I've had a fairly slow and sedate one which was scary enough.

We have different definitions of short. Upstate New York to southwest Florida isn't what I would call short.
I see what you did there... Even if no one else did. LOL

Even in a King Air 350, you are looking at 1000 pph down low and 600 pph in the flight levels. It has an extremely annoying cabin altitude warning system, so that helps.
