As someone younger who grew up in a time where you would get a cell phone during teenage years, I can't say I empathize with your view of "my device" vs "interruption device".
Although there are likely an overwhelming majority of my peers who do have an interruption device phone, I refuse my phone not be My device, and I explicitly buy phones that I know I can customize (unlock bootloaders, flash roms, or simply just know it has the interop capabilities I need to make it my own). Where this is in opposition with your statement is that I do have social media, mail and even work email on my phone, I just chose to customize it to not be interrupting to work and personal life (though obviously that line is different for everyone).
Of course I'm not saying your way is wrong at all, just sharing my experience.
Not GP but this thread is great. I was among the first in my city school to get a cell phone and text in ~2001, and then the last to get an iPhone in ~2015, and then stop carrying it most of the time in ~2016/in airplane mode and then cease to have a cell phone at all in ~2022. Texting kinda ceased after 2013 when I moved states temporarily and went thru some stuff, never resumed.
I'm notoriously unreachable, perhaps even offensively unreachable, and I'm starting to look for time and money savings to justify getting a new one/repairing the SE if possible. Eg. I'd save $10+/mo in Starbucks refills if I had that app, enough of those cases to cover the bill.
My next phone will be like parent poster's. I had iOS setup with no notifications except Venmo and a priority email alias. Currently I'm using an Unbuntu laptop where I can get to Google Voice that was activated with a Mint Mobile trial on Starbucks wifi. Am homeless, actually been able to secure and hold a couple labor/hospitality jobs like this.
