I wonder if they get the $GOD level reference you just made... :)

Back to the topic of what's the security update lifetime, I think there are
two overlapping answers to that question - one of which is "forever"
and the other of which is about three to five years for Google/Samsung.

For example, my Samsung shipped in 2021 with Android 11 which then moved to
Android 12 and now to Android 13 while Frank Slootweg's Samsung shipped
with Android 10 and he recently updated his to Android 13 - all the time
with two types of constant weekly concomitant Android "security updates".

Notice though that the two types of security updates are both the same and
different at the same time - which I think is the source of confusion...
"If you don't already know, security patches and Google System updates
aren't the same. You might be familiar with the former because those
arrive as a software update for your phone. Unless you have auto-updates
turned on, you have to manually download and install the monthly security
patches. They fix various privacy and security vulnerabilities found on
Google's version of Android as well as custom skins supplied on top
by your phone's manufacturer.

Google System updates, meanwhile, are fully automated.

Originally referred to as Project Mainline, these updates fix bugs
discovered in various OS components like device connectivity,
location services, media services, Emergency alerts, and others.
Sometimes, they may also bring new features or enhancements."

What it says is that Google is publishing _monthly_ a changelog of both
a. Security updates via security updates, and,
b. Security updates via Google Play system update updates.

Notice that says "Every week, the Google Play Store provides...", so the
update frequency is literally weekly, forever (as far as anyone knows).

The latest appears to be the October Google Play system updates update.
"Available through Google Play Store v37.8 updated on 10/2/2023"

In summary, "some" security updates on Android last only five years,
while other security updates last forever (Android 10 and above).

Forever here means nobody knows of any EOL date and even if there were an
EOL date, all Google Play System updates are donated to the AOSP community.
