10m is larger than current resident counts, so people moving in can decide now if they want to move with uncertainty. It is not what everyone would like, but it is more understandable that recent Swedish changes, for example.

> doesn’t pose any constraints on the type of data.

logic, raw disk is also a database. One just need to add block level replication to other nodes to build a replicated/ HA database.

We may not agree, but anything not providing transactions across logically related multiple data read/ update operations is not a database.

> multiple instances to provide the same data

is easy and done by a bunch of software out there, but

> multiple instances to provide the same data on non-shared memory computers, with consistency

is a really hard problem, and no one has been able to solve it yet without introducing other problems to be considered (giving up on fast performance being one of the most visible one) by architects/ developers.

To put the simple terms... App writes to node-A, node-A (/process on node-A) crashes before change is synced from node-A to node-B, data is lost.

This is true for redis and true for postgresql/ mysql or any similar database. Difference between redis and a "database" is that database protects against this problem by writing change to durable storage before telling app that write is successful. Redis

So if one wants to have a consistent session storage, one should use a proper database or use AOF redis persistense with single node (https://chatgpt.com/s/t_6a24ab818e2881918db959cec8d8cc2d)

No, redis is a memory cache, with some ACID like features bolt on.

Even real databases have hard time maintaining consistency across nodes. CAP is a real constraint.

Just to put things in context, https://www.bbc.com/news/articles/ce8444gex65o shares income for a good number of people now a days. (note that many of those workers are taking care of a family of 2+ members, most of the time)

That is way to high recurring cost that many won't be able to afford. One could get a second hand calculator or even computer, and then additional resources needed was one's willingness. With mandating AI usage, we'd only increase the gap of haves and have-nots. I personally do not like the idea.

I personally have no qualms about one criminal extorted by another, specially if their fued is making world better for everyone.

But if I interpret the question with line of thinking "should I anticipate right/ full answers despite incorrect/ incomplete inputs?" I think Baggage was pointing out the problem in the logic why such questions should arise.

I would expect the question to be phrased "under what circumstances the machine with provide wrong outputs?", and would have hoped for Babbage (or may be anyone) explaining many ways how things could go wrong.

I guess many of us quality for british parliament.
