Ai is not "learning". These are autocomplete algorithms. They don't understand it. As said copying into a database and then just autocompleting based on probability is not learning and thinking. There is no reasoning. Its fundamentally different to how humans learn.
Stealing has a definition: “Stealing is the act of taking, using, or appropriating another person’s property, ideas, or services without right, permission, or legal consent, with the intention of permanently depriving the true owner of their use or value”
Whats the source for the definition and why is that definition correct and mine wrong? Did you ask an Ai? That's probably you don't have a source.
Permanently depriving the owner. It means something is taken and is now gone. Nothing is missing. Nothing was stolen.
That's when you talk about real goods, not code. You forgot your Ai to tell that. In software and art stealing is if you take it and use it without permission, and possibly give no credit.
In example, if you see a photo on the net that is sold to you, but you copy it and use it without permission, without respecting the license, then its stolen image. The owner does not know, nor did you rob the ability for him to use the image. Another example is to take an Open Source project that is licensed under GPL, but then use it without respecting the license and sell the product on Steam for money. That is stolen Open Source project.
