If you could only have 1GB of entertainment data, what would it be?
You are going away, to some place isolated... in space, of course. You will only be around one other person. You can take an allotment if 1GB of personal media with you (text, video, music, games, pics, etc.) that you will be able to access in your free time indefinitely at will.
The other person will also take 1GB with them, but you won't be able to talk to them until you're on the journey.
You will have access to any knowledge resources to perform your function and keep you alive. You will never return to a point where you can get new external media. Any additional media you ever access would have to be created by you and or your travel partner with what you have access to.
You will also not know the sex of your partner, but they have willingly taken the same risks to embark on the journey as yourself, and will have a similar mission.
Would use 1/2 on ebooks, 1/2 on passible quality music I'd give up some quality for size reduction. I'd probably save a little space for a sudoku game.
I have read somewhere that some text can be compressed incredibly efficiently in some AI models. The issue being that the compressed data is worthless without the model and power to recover it.
20 years ago, I used to have custom playlists that I'd load onto a 64mb SD card for my commute. A 64kbit wma file is surprisingly listenable. You can fit more than a standard album onto 64mb. I'm trying to remember now how much, probably 20-25 songs?
At that compression rate, I expect you can get a few hundred songs into half a GB. Of course, picking them would be its own challenge! It'd be the most curated playlist in history.
