That's... not quite the same thing.

More like, everybody has their own sourdough starter. Some people sell theirs, some people give it out for free. Someone goes from house to house to make a super-starter by collecting pieces from each house. Then someone uses that starter to sell a patented bread

Ok it's not a great analogy either. Maybe we need to stop trying to reduce the complexities of digital so much

Not the same. Probably theft laws are more similar. A thief steals a knife and sells it to a knife seller. The knife seller sells you the knife. Under law, stolen property belong to the person it was stolen from, and sales are not valid. The original owner of the knife claims it back from you.

But being digital, the knife was just copied and the original owner still has one, but you also have theirs without their permission. So there's much less sympathy for the victim.

Unless the hammer automatically chooses it's target and will (sometimes) hit a human in the head all on it's own unless the owner is paying sufficient attention to check it's target on each swing and validate that it's not a human head.... not really the same thing.

we need another AI in example, if someone's AI car automatically random hit people, do not company have some responsibility?

Isn’t that what Biden wants to do with gun makers?
