Sorry if this is an easy-answerable question - but by open we can download this and use totally offline if now or in the future if we have hardware capable? Seems like a great thing to archive if the world falls apart (said half-jokingly)

Yes, but you'll need some pretty massive hardware.
You could buy five Strix Halo systems at $2000 each, network them and run it.
Rough estimage: 12.5:2.2 so you should get around 5.5 tokens/s.
