The GPL arose from Stallman's frustration at not having access to the source code for a printer driver that was causing him grief.
In a world where he could have just said "Please create a PDP-whatever driver for an IBM-whatever printer," there never would have been a GPL. In that sense AI represents the fulfillment of his vision, not a refutation or violation.
I'd be surprised if he saw it that way, of course.
But that isn't the same code that you were running before. And like, let's not forget GPLv3: "please give me the code for a mobile OS that could run on an iPhone" does not in any way help me modify the code running on MY iPhone.
The safeguards will prevent the AI from reproducing the proprietary drivers for the IBM-whatever printer, and it will not provide code that breaks the DRM that exist to prevent third-party drivers from working with the printer. There will however be no such safeguards or filters to prevent IBM to write a proprietary driver for their next printer, using existing GPL drivers as a building block.
Code will only ever go in one direction here.
