6:15-7:45: A Brief History of Artificial Intelligence
Up until early 2023, I regularly said AI would always have a bright future—and I didn't mean that as a compliment. Sure, deep learning had made us good at building very impressive classifiers in the decade or so prior, but for so long, human-like intelligence was just five years in the future—and that made me a skeptic. Things are different now, but how much skepticism is still warranted? What is it that we've got on our hands? What changes is modern AI bringing with it? Like with so many other questions, the answers are easier if we understand where we've come from.

Beginning with the Turing Test itself, the famous Dartmouth Conference of 1956, and the Perceptron of 1957, we'll trace decades of disappointment and broken promises as we tried to realize the true potential of computing, at the same time grasping for an understanding of what it means to be human. Taking a close look at various technologies along the way, we'll arrive in the 21st century, the revival of neural networks, the advent of the Transformer, and a revolutionary new technology category that has prompted oracles of weal and woe from our most optimistic and apocalyptic technology prophets.

Standing on the edge of the unknown, what elements of the 75-year-old promise have we realized? A close examination gives us a better view of our immediate future as technologists and insight into what it means to be human.

6:15-7:45: Structured Concurrency in Action

In Java 25, the structured concurrency API sees its fifth preview with considerable changes over previous iterations. With chances being good that it will finalize without a further overhaul, let's put it into action and explore how to:

* structure concurrent code
* process and propagate errors and cancellation
* observe thread relationships
* refactor from a reactive approach

After this presentation, you'll be ready to put the structured concurrency API into action in your project.

About Nicolai Parlog
Nicolai (aka nipafx) is a Java enthusiast focused on language features, core APIs, and runtime evolution with a passion for learning and sharing. He does that mostly at conferences and in his biweekly Inside Java Newscast, but also occasionally in podcasts, live streams, articles, and books - more on all that on nipafx.dev. He's a Java Developer Advocate at Oracle and otherwise best known for his haircut.
