Yeah, I really wish it wasn't like this, but replacing a phone's OS is a lot more like flashing a custom bios than installing an OS on a hard drive.
Temple OS wasn't Unix-like.
Also it gets way too much attention as is IMO. Its the only hobby OS project people know about, purely because 4chan turned its mentally ill creator into a meme.
In addition to what groet said, I'll add that this is a little bit like asking "what's the difference between a public library and Amazon?".
Yes, there are other public libraries you could go to if the one you subscribe to didn't have something you wanted or 'went bad' somehow, but the most important difference is you don't have an antagonistic relationship with your public library. Your public library doesn't have a financial incentive to try to trap you or screw you over.
Besides the basics (operating systems, compilers, office, CAD, database, etc software):
-
A copy of open street map together with the linked Wikipedia articles, along with the software to view and edit them. I know you said no wikipedia, (since that's pretty much a given), but this is basically the hitchhiker's guide to the galaxy.
-
A copy of Godot's editor so people can still make games.
-
As many games as I could fit in the remaining space, concentrating on the ones that give you the most bang for your buck in terms of space.
There's a clear cause:
Where so many other cities have decided that they can't have public benches Vienna has decided to put in public hammocks:
It was cooked up by Milton Friedman, one of the grandfathers of American free market libertarianism.
The whole impetus of UBI was to eliminate traditional social services because, it is argued, there's no way that a government institution could be as efficient or effective as a free market.
And make no mistake, even modern proponents of UBI such as Andrew Yang propose funding it by hollowing out existing social services.
Like, yeah, UBI is better than having literally no social support at all, but the fact that its seen as this ultra-leftist idea, to the point that we apparently can't even conceive of how it could possibly "not be left enough", is an indication of how far right mainstream politics has shifted.
The right to free speech and the right to peaceably assemble hasn't been respected at any point during US history.
Not immediately after the country was formed when they signed the sedition act into law.
Not while people were protesting for abolitionism.
Not while people were protesting for women's suffrage.
Not while people held demonstrations while on strike.
Not during the cold war and red scare.
Not during the civil rights movement.
Not during the George Floyd protests.
They're not going to start now.
I would add Project Gutenberg and Open Street Map to your list.
Reminds me a lot of this image:
Star Wars is Dune for people that love WWII and samurai movies.
Dune is the Foundation series for people that like mushrooms more than math and have weird ideas about women fueled by angst over their wife divorcing them.
This is plainly false.
The error stack-up from the imprecision of a phone's MEMS sensors would make positioning basically impossible after a couple of dozen feet, let alone after hours of walking around.
There are experimental inertial navigation systems that can do what you describe, but they use ultra sensitive magnetometers to detect tiny changes in the behavior of laser suspended ultra cold gas clouds that are only a few hundred atoms large. That is not inside your phone.
