That's an interesting point, but I think you're jumping the gun by a few decades at least. If Stack Overflow and GPT type stuff eventually makes software copyright essentially non-existent then of course the GPL will be obsolete. But we're not there yet. Not by a long way.
I keep repeating that if it's fair use and doesn't violate license or regurgitate entire blocks of code verbatim… why doesn't microsoft train it on the projects of the paying users and their own?
