Im also confused. Do these people not have some sort of version control and backups? Even if the AI did it, no one has backups? Did the ai also delete the backups and repos? If the building burnt down, would they be in the same situation, it just wouldnt make it to the news?

Hydrogen can be made from water. You get oxygen too.

By wasting a lot of electricity.

Just curious, how is the majority of hydrogen produced/mined/farmed now?

I kinda always assumed it was electrolysis just because the process is so simple.

Also, those ships themselves cant run on batteries. So some fossil or liquid fuels would still be needed in some applications.
