More important would be to preserve a very thorough and accurate recording of everything we’ve done so any future civilization could analyze it and determine what we did wrong and how to avoid it. More importantly though we should be working on solving the problems we have and making sure our current civilization doesn’t fail.
Spending a lot of effort on something like this seems akin to writing a letter to the next tenant for your apartment while you should be working to keep your job so you can stay in the apartment.
I think so too. I don't think that preserving technological progress is as important as preserving history.
The focus should be mainly history with some foundational scientific works.
Or don't try to preserve anything. If a future civilization needs it then the current civilization obviously messed up big time and don't deserve to say anything else. Our shameful wreckage will be ubiquitous and apparent to any future inhabitants. Just die quietly and leave it at that.
