A person is not a program. A program that ...
A program is an extension of a person. Clearly, I can not sue a program in court. But I can sue the person who wrote the program, or who sold it, or who uses it. But in all cases, the basic causal relationship of "what made the crime happen" is the program.
The program has no analytical ability or comprehension ability like you. It's simply processing the works of people to generate something. This is called theft.
Nonsense. Example: I write a program that analyzes the pressure in my home water system, and how often the pumps have to run, with the outside temperature, the water level in the well, and the phase of Aquarius. I will find certain results (irrigation uses a lot of water, it takes longer to pump water further uphill). I control the input data, which I have carefully collected over the last few years. To calculate the positions of Jupiter and Aquarius, I use well-known public domain formulas from an astronomy textbook.
Where exactly is the theft here? So your assertion that all programs that process data commit theft is balderdash.
Next: The works of Shakespeare are in the public domain (he's been dead for a while). I use an LLM to write the perfect love sonnet, and use it in an attempt to seduce my wife into cooking a romantic dinner (we've been married for over 30 years). Am I stealing from Shakespeare? Note that my wife would probably slap me, and if I tried it three times in a row, she'd even use a heavy and large object to hit me. Anyway, other than the very serious crimes of literary stupidity and domestic violence, where is the theft here?
People publish things all the time. Shakespeare published his works. Einstein published E=mc2. Linus T publishes the Linux kernels. They all have some copyright. But I'm allowed to read all of these published works, and make myself a smarter human, and then use that smartness for my own purposes (like getting a nice dinner). We have copyright laws to make sure the balance of equity between the people writing and publishing things, and the people reading and using things remains fair and equitable. Those laws work (pretty badly), but they are the best we have, and they keep things somewhat in order.
LLMs don't change the concept behind that. They read all these works that are published and sometimes copyrighted, and they "make themselves smarter". The difference is that the economics of the system is completely changed: LLMs learn faster and broader, and create results more cheaply (alas also usually unreliably). For that reason, the existing "social contract" between author and user may not be appropriate any longer. But right now, we don't have a new set of laws to govern this, and using the existing ones in the new situation is difficult and may give counter-intuitive results.
