The Chardet dispute and the future of licenses

The open source community is buzzing about a license change in the Python library chardet, used for character encoding detection. Dan Blanchard, the maintainer, released a new version under a different license, sparking a heated debate.

The issue highlights a potential vulnerability not only for open source licenses, but also for commercial ones. The advent of artificial intelligence and its ability to learn and replicate software functionality raises doubts about the protection offered by traditional licenses. If an AI model can be trained on licensed code and then used to create similar software, how is copyright protected?
