Since they moved macOS off version 10.x (finally), "Apple's crack marketing team" left the desert (Mojave) for the Pacific coast. Unfortunately, they didn't plan the trip carefully, so they started at Big Sur with macOS 11, went north to Monterey for macOS 12, then turned around and headed back south to Ventura for macOS 13. At least those locations are in alphabetical order -- but with Ventura they seem to have painted themselves into a corner.
So will macOS 14 be further south (Carlsbad?) or back north (Eureka?) -- stay tuned...
(Straying a little off topic to provide the following hint:)
There's a setting for this in System Preferences > Keyboard > Keyboard. My recollection is that this was previously a checkbox that toggled the "double-Fn to invoke Siri" function on and off, but as of Big Sur (at least) this is now a popup menu control, where the choices are "Change Input Source", "Show Emoji & Symbols", "Start Dictation (Press Fn Twice)", and "Do Nothing".
My test M1 machine was set up from scratch last year (i.e. no account migration) and has "Do Nothing" selected here, so I can't confirm that "Change Input Source" is the default for new users, but its position as the first item on the menu is suggestive.
I may be dating myself somewhat here.
