I've been digging into the rabbit hole for a few months. Been switching to Linux, FOSS everything I can, trying to go to smaller sites, the least dubious social media, VPN, trusted mail, etc etc

But lately I've been in a rough state mentally (I say lately but it's always been with me) and having GPT guide me and being able to just dictate what I think helps me a lot on various levels, for various reasons.
But at this point, using ChatGPT with a mic, isn't this basically cancelling every effort I've made? (using it in the first place anyway) I'm weak and it helps me, should I just throw my efforts out of the window and just say I don't care about privacy anymore and use whatever everyone uses? (on one hand, I've found alternatives for almost everything, so I could keep on using those, but also, again, if I keep on using GPT on a regular basis, this is probably the worst threat the future has to offer in termes of privacy, so...I'm lost)

The only Pixel I have is a Pixel 3XL which is not supported anymore for updates. A few questions. does that mean at some point you have to buy a new phone all the time? How long are they supported, do I need the buy the newest one everytime to have a decently long support? If I can install Calyx, but have already degoogled my phone, is Calyx still useful? But I suppose at this point it's still better to get a Pixel anyway and install Graphene which is supposedly better? how risky is it to run an unsupported phone like my Pixel 3XL? What can happen?
