Some good advice in the comments. Perhaps you could take some important open source systems in the data science space, and then use AI to help you deeply understand how they’re built and why they were built that way.

That will give you hands-on with the new AI tools, and deepen your understanding of key open source systems - far more than going through online tutorials. That might even lead you to making some contributions to the projects, which in turn will help you answer the interview question “so what have you been up to?”
