From my experience with modern software and services, the actual practice of QA has plainly atrophied.

In my first gig (~30 years ago), QA could hold up a release even if our CTO and President were breathing down their necks, and every SDE bug-hunted hard throughout the programs.

Now QA (if they even exist) are forced to punt thousands of issues and live with inertial debt. Devs are hostile to QA and reject responsibility constantly.

Back to the OP, these things aren't calculable, but they'll kill businesses every time.

Continuous delivery really killed QA.

that's not the role of QA to be a gatekeeper, they give the CTO and President information on the bugs and testing but it's a business decision to ship or not

I’m not a native English speaker, but isn’t gatekeeping exactly that? Blocking suspicious entities unless they’re allowed through by someone higher in the hierarchy?
