Termux on Android devices

To give an example yesterday walking down the street I had an idea for a prototype (basically every morning my phone would generate an ePub with calendar, map of the area, notes, articles to read, etc) but I didn't use some fancy voice assistant, no I started Termux on my phone, mkdir, echo idea > file, etc.

I have notes on my wiki on https://fabien.benetou.fr/Content/SwappingPartsOfTheRestrictionStack on doing this kind of stuff on more than phones, VR headset, IoT, etc. Typically the heuristic is to still by modern hardware flash an open source firmware or OS then connect it to your tools that are already not enshittified or de-enshittified
