Too many people are worried about losing their jobs and homes because of AI. For 90% of the population, AI is very helpful; however, over time, prices will most likely skyrocket since people will become used to getting better results in less time. Still, with the development of local AI, I think there will be alternatives once we reach that point.

What kind of global collapse? Nuclear meltdown? You can't prepare for that you just get evaporated in less than 5 seconds so at least you will not suffer too much.

My take would be using grapheneos and give the duress pin when asked for it, that way if they put the pin the entire phone gets wiped.
I know I'm not answering your question directly but if you use lineageos with an unlocked bootloader the best you can do is deny to give the passcode but eventually depending on their resources they will get in.
