I’m not sure what would be acceptable output for a code generation tool if rewriting the examples isn’t ok and reimplementing something that performs the same function still isn’t ok. Are we automatically granting de-facto code patents on all published code now?
There are two worlds.
In one, everytime someone publishes code with a license attached, they've taken a chunk out of the set of valid lines of software capable of being permissibly written without license encumberance. This is the world the poster you are replying to is imagining we're headed toward, and this case basically does a fantastic job of laying a test case/precedent for.
The other world, is one where everyone accepts all programming code is math, and copyrighting things is like erecting artificial barriers to facilitate information asymmetry. I.e. trying to own 2 + 2. In this second hypothetical world, we summarily reject IP as a thing.
The 2nd world is what I'd rather live in, as the first truly feels more and more like hell to me. However, given the first one is the world we're in, I'd like to see the mental gymnastics employed to undermine Microsoft's original software philosophy.
EDIT: Voir dire will be a hoot. Any wagers on how many software people make it onto the jury if any?
If this were true of copyright, we would’ve run out of permissible novels a long time ago. There’s plenty to complain about with how software IP works, but copyright seems pretty sane. The alternative of protecting IP via trade secret is not a world I want to live in. That seems bad for open source.
The central idea of programming languages is that the grammar is very restrictive compared to natural languages. It's quite likely that, with the exception of variable names and whitespace, some function you wrote to implement a circular buffer is coincidentally identical to code that exists in Sony's or Lockheed Martin's codebases.
Plus there's the birthday problem -- coincidences can happen way more than you expect. And even with prose, constraints like non-fiction can narrow things down quickly. If everyone on HN had to write a theee-sentence summary of, say, how a bicycle works, there would probably be coincidentally identical summaries.
