Software that’s “just a tool” can lock you down and out of what you can do with it.
AI is not “just a tool”. It is highly unethical.
It harms the environment, it harms actual developers, it introduces all sorts of legal issues where copyright is only one of them, it locks you in to a vendor, it makes you dependent of giant tech companies that steal your data and want to monetize your work.
Linus seems to ignore that or does not care about it.
