Unfortunately the "with significant human input" case hasn't been tried yet. As with most of these things the team that spends the most on lawyers wins the vast majority of the time, so corpos will get the case law.

I'm hoping that the "with significant human input" case turns out to be a massive own goal and basically breaks software copyright a few years down the line when anyone can re-implement any software.

Of course that's when lobbying buys a law to override the case law. Sigh.
