In my talk I will argue that we can do much better by relying in a systematic way on types and capabilities.

AI agents are taking over many tasks that required humans before. This could be very good for productivity but how can we possibly trust our agents? There are a multitude of known ways an agent could go wrong, including prompt injections or plain hallucinations. The current techniques to control agent behavior are patchy and rudimentary, they certainly don't instill trust.
In my talk I will argue that we can do much better by relying in a systematic way on types and capabilities. We can use them to make not only bad states but also bad actions unrepresentable. This points us to a possible future where an inherently untrustworthy LLM agent can be trusted to stay within defined parameters when put in the right environment.
We'll explore type classes in Scala 3, using its new rules for givens, extension methods, and mechanisms for automatic derivation via mirrors or macros.
In this talk, I will introduce the highlights of what to look forward to in Scala 3.9 LTS, as well as how to think about the upcoming new release.
In this talk, I will present insights from running the Open Community Build, where we continuously build and migrate nearly 2,000 open-source projects to the newest Scala Next versions, from scratch, every week.
Do you like it when compiler generates the boring code for you? Fast, mundane, boring-but-error-prone code? Do you need to implement such a code generator yourself? Have you found out that Shapeless/Mirrors bend your brain a bit too much?
In this presentation, I will demonstrate how we leveraged the strengths of Scala and TypeScript to develop a collaborative text editor that meets the strictest standards for security, performance, and real-time collaboration.
