The video is 3 hours long though, and I'm not sure the text he shows is available.

At this point he's talking about left leaning vs right leaning trees, after having already talked about one of them: https://youtu.be/fIPO4G42wYE?t=2256&si=aanthLGe-q8ntZez

I think I saw MidnightBSD said it seemed like they were thinking of iOS when they made this law, and I agree.

If you did make a child account on a desktop system, and it had some age category signal that programs and scripts can access ... do you have to prevent the child from making their own programs and scripts, since they could be modified versions of the apps that are supposed to have access to the age signal? So are they not allowed to do programming and app development, or even scripting from a child account? Not so much of a problem on iOS where these are already heavily restricted.

On the other hand, if my Android phone had allowed me to set up an account labelled "adult" and another "child", and disable side-loading on the child account except for specific apps I approve, and then the discord app would stop bugging me for photo-based age identification on the adult account, and would prevent access to adult discord channels on the child account but not the adult account, that sounds fine. Still not sure what to do about programming apps on the child account, maybe parents could decide which ones to allow, but there could be similar problems to deciding this question for a desktop system. Also, it would be good to have a quick-switch - if I want to let my hypothetical child play approved games on the phone, there shouldn't be a cumbersome log out/log in process, just a quick change change that changes the age signal, and tells discord etc not to allow access to adult channels until the signal changes again.

Seems no worse than what mobile OSes already do and not that bad a feature for a modern general use OS (except if you monitor someone's age bracket and noticed the exact day they change, you can work out their precise date of birth.) It does seem unsuitable to force it to be added to embedded OSes, freedos, CP/M and historical/retro OSes in general.

I don't have a solution, though the only two categories of solution I can think of are forbidding people from developing and distributing certain types of software, or forbidding people from distributing hardware that can run unapproved software (at least if they are PC's that can run AI, arduinos with a few kB of RAM could be allowed, and iPads could be allowed to run ZX81 emulators which could run unapproved code). The first category would be less drastic as it would only need to affect some subset of AI related software, but is also hard to get right and make work. Not saying either of these ideas are better than doing nothing.

I imagine some will, but hopefully that won't be the norm. Beehaw isn't doing it.

There's probably been similar stuff on twitter though - blacklists where you get added for following someone else on the blacklist

Tumblr has some pretty good discussion about movies and books.

Twitter not so good for discussion because off the length limit, but there's plenty of people posting concise observations and jokes rather than posting about themselves.

On both systems, people can reply to content from strangers, and there's lots of conflict arising from that.

I do think Tumblr would be improved by making it easier to have discussions that don't go to all your followers by default, for example like on Twitter where if you tag people at the start of your tweet, it doesn't go into the main feed for your followers who aren't tagged.

Or you can go all the way to partitioning a system into topics, as with Reddit. I wouldn't call that a social network though, you don't just casually start a conversation with people you've chosen to connect with, you start a conversation with a subreddit.

Do the apps or the users manage security choices like these?

They want the ease of use and security of a phone OS and app store, but they also don't want the data stuck in separate silos. I'm not sure if the idea is to have isolation between apps like iOS has or what.

Could get complex if people vote in the opposing party's primary though.

Is there a technical term for that in statistics?

It's like trying to get a representative sample, but only representative in one specific way (topic), and deliberately non representative in another (interestingness)

I think this could get at one of the things people mean, and it might be interesting to see how this trades off against overall accuracy or representativeness in other categories.

I'm not saying this is acceptable, but it seems to be happening.

Or if not a direct translation of a Turing machine, then some other Turing complete system.

As far as I know, no one has done this, but if it is possible, one implication would be that you couldn't prove whether the process of recursively unzipping a file could continue forever, or would halt.
