Ask HN: Where to start with AI as a software engineer after a long sabbatical?

I took a long sabbatical for part of 2024 and all of 2025. When I left the industry, coding with AI tools was not yet mainstream, particularly at the big tech company where I worked.

I am now looking to step back into a senior software engineer role, but the industry has evolved. What are some things I should know or resources I should review to get up to speed with the latest AI enhanced ways of building software? I'm interested in preparing for both real-world and interview scenarios.
