It will have unlocked bootloader and quite standard SoC, so you will be able to install PostmarketOS or any other mobile Linux on it.
But in that case you might as well buy FairPhone 5 right now and do the same to it.

Until it is suddenly there, while you are unprepared to do anything about it.

Matrix seems like the one with most potential to develop into a 1:1 Discord alternative.
Then you have XMPP, Mattermost, RocketChat, whatever Revolt.chat renamed itself into, etc.

Yes, and so is a virtual machine. I’m thinking install Linux to disk so that it can then run directly on hardware.

Yes, this is something that should be taken into account when designing this software.
Set dual-boot as a default / design UI in a way that offers dual-boot as a preferred option.
And many other technical issues will probably appear that will have to be figured out.
But I think that at least even thinking about this is a good start.
Also, this reminds me of 2013, when people accidentally nuked their Windows installs with Linux because they wanted to get the Tux in Team Fortress 2 (Valve gave it to people who played Linux version of TF2).

and this year Android also surpasses Ubuntu for personal use (29% vs. 28%).

lol why bother with same OS category when you can just compare across whichever fields you want

Apparently not good enough lol. Still marked as bot.

Oh, this video by Digital Foundry is also relevant:

I’m sure that there are games (either video games or IRL physical games) designed for this. Some simple “here are some possible instructions, use them to achieve some goal” thing.
Something like described here:
https://wiredme.com/blog/active-coding-games-for-kids/
But I am interested in knowing more examples of such games. Is there any Wikipedia article for this category of games? Is there any list with more of them described?

lolwat. can you explain the reasoning in your second paragraph?
Also I’m not sure that your definition of Enshittification is correct.

My first Android phone was Motorola Dext, second one was HTC Desire Z, which I held on to for a long time. By the time I had to replace it, there were no slide-out keyboard phones any more.
Then some time later F(x)tek X1 Pro was released. Looked like a perfect phone for me, but was too expensive, so I did not get it. But now that it’s time is over as well, I look at the reviews and see that I did not miss much.
So now I am sadly on a glassy rectangle like everyone else, but I do carry a collapsable bluetooth keyboard around with me sometimes, so that I can still type some longer text in a proper way.

Also, I solved my no-headphone-jack issue by getting USB-C headphones. And there are USB-C to 3.5 jack adapters if you need to connect existing headphones or other equipment. So I don’t really get how this “I miss a hole” is everywhere and lasts for so long.

The best kind of correct

YUNOHost iso is basically just Debian, but the one-click-install for various self-hosted things is it’s primary purpose. All done through web interface.

It does work, I have been using it for a long time now in context of my interest of using a phone as a PC.

Thing is that with just termux, you get just the android/termux environment.
There is a way to get more familiar Linux environments running on your phone by using proot from within termux.
https://wiki.termux.com/wiki/PRoot
For example, using that you can install ARM version of Manjaro, which is basically the same thing that you would run on Raspberry Pi.
But everything in there runs a bit slower, because Proot is some layer that takes up a bit of performance.
Benefit of that is that you can run some Linux software that is not found within Termux packages, but is available in the repositories of other distros. Libreoffice is one such example.

LineageOS 22.2 (on FP4) does not seem to have that option yet.
At least, it is not listed in the developer options.
You can find it if you tap on the search button within developer options (or just general settings, as that also includes results from developer options) and type “terminal” or “linux”.
The (Experimental) Run Linux terminal on Android result shows up.
But after you tap on that, you see that toggle is greyed out. Can’t be enabled.

I am interested in getting that to work, so any help is appreciated.
There is hopefully some ADB command or something that forcefully enables Linux environment.

Make an app that guides users when folding the phone

Title reminds me of the thing that Lous Rossmann initiated:

which seems like it could be a subset of the thing in OP

Supposedly Google would have better time taking care of just one consumer OS instead of two, so Android is getting some PC features so that it will be able to replace ChromeOS in the future.
