I think Infomaniak's kSuite, CryptPad, or Drime are nearly on par. www.jesperjuul.net/ludologist/2...

You mean it's just a general lack of (data) literacy? I see the point. People also used to take Google to be an oracle.

2) As I recall Piaget, he has a similar distinction (named in reverse!) between "regularities" (what governs the activity, such as throwing marbles) and "rules" (the goal).

Probably yes (the rules are what govern the game). But it is perfectly possible to make distinction. I think there are two variations.
1) The Bernard Suits argument that there is a pre-existing "goal", and "the rules/game" - constitute a limitation of what players can do.

And why even ask us the question?

Spoiler: This refers to AIs (as in LLMs) running on your own server, specifically Meta's Llama AI.

Thanks for letting me know! It is available from the publisher, but Amazon in Europe has it out of stock sometimes. I think Thalia.de has it

The software is there, but the storefront can be improved. Don't take my word for it. Try putting a non-technical user in front of the site. Don't tell them anything and see if they a) realize that Nextcloud can be used for an office suite b) can sign up and get to said office suite on their own.

I disagree. NextCloud a software platform for installing on a server, it's not something a regular end-user can use to replace an office suite.

Yes, people refer a lot to the site, but it's incomplete to the point of doing more harm than good. The "document collaboration services" lists five items, the four of which are not relevant for end-users, and three of the four services I review are missing.

I mention the "what about Proton" problem in the post: When looking for a Google Docs / Office 365 replacement (Word/Excel/PowerPoint editing) you will invariably be recommended an email service with note-taking features, which is something very different!

Yes, but unfortunately if I go to Alternativeto and look for a Google Docs alternative in Europe, I get exactly zero relevant end-user options for editing Word documents. If I look for Google Suite alternatives, I get only kSuite and Contactoffice, so it's really difficult to find.

OK! The how-to is on my TODO list.

I find that it's just one step at a time. Your email, your docs, your photos, but it is work.
