Happy Wednesday 👋 and welcome to this very special edition of Tech Talks Weekly!

Following tradition, I’ve put together a complete list of the top 100 most watched Software Engineering talks presented in 2025 across almost every Software Engineering conference around the world.

It’s probably no surprise that most of the talks are about AI. Exactly one year ago, in March 2025, we heard AI will write 100% of the code by the end of the year. I think this prediction was remarkably accurate and it’s is clearly reflected in this year’s talks.

The most-watched talk this year is AWS re:Invent 2025 keynote by Werner Vogels. I’ve always been a big fan of Werner’s keynotes. Sadly, this year marked his final re:Invent keynote and his message was simple yet profound: the future belongs to developers who are capable of taking full ownership, thinking in systems, staying extremely curious, and use AI with intention. He called it the “Renaissance developer”. You’ll find the link below.

That said, there is a pattern you’ll observe among the rest: instead of asking whether AI will change software engineering, most speakers are now focused on how to work effectively with it. At the same time, many talks also cover the core challenges that come with this transition: reliability (yes, some teams now have 2x more incidents), security (well… is there any, really?), and the fact that having strong engineering skills are still essential (because now tech debt can be generated 10x faster!).

Enough talking.

Expect your watchlist to grow!
