But you do pay for all of that in todays society.
Teachers are paid, tuition to schools is paid, feedback from tutors is paid, textbooks are paid for, copies of books are paid for, movies and TV are paid for. The experience you learn on the job is paid for via yours or your coworker’s salary.
I get the argument that it’s not copying it’s learning, but it’s also very different than a human learning by observation.
And if learning weights is okay, is it okay to train an AI with the structure designed to reproduce Shrek, then sell the AI? I think ShrekAI would be illegal in most countries. It’s a blurry question that we need to think about.
