The slides from my keynote at AgenticOS 2026 in Prague are now online and archived on Zenodo with a DOI. The talk asks what an agent runtime should actually guarantee, and argues that we need a kind of POSIX for agents before the semantics of today's runtimes harden.

ForkOps at SWGeno 2026 and Whose Oracle Is It? at APR 2026, both workshops co-located with ASE in Munich. Generated software needs fleet operations, and generated patches need an authority problem solved.

Two papers at AgenticOS 2026 and one at PACMI 2026, both workshops co-located with SOSP in Prague. And I will be giving the keynote at AgenticOS. If you are attending either workshop, come say hi.

Two new papers with Quentin Botha and Christoph Siebenbrunner at BCCA 2026 in Barcelona. Agent Flight Recorder gives long-horizon agents a tamper-evident audit trail anyone can verify, and Bonded Recourse settles the harm an agent leaves behind through smart contracts.

Everyone is predicting that AI will flatten the software stack into one English-speaking agent, until nothing of the old software remains. It will not go that far. Complexity is conserved, the end-to-end principle still collects its debt, and the stack does not flatten all the way down. It sorts itself by what you can afford to trust.

New paper with Akanksha Narula and Mofasshara Rafique at ICML 2026 in Seoul. Incidental prompt cues silently decide which algorithm an LLM ships, even when every output passes the same tests.

I am giving the keynote at EuroMLSys 2026 in Edinburgh. A short teaser on what happens to software when code becomes disposable.

New paper with Mofasshara Rafique at EuroMLSys 2026 in Edinburgh. Classical virtual memory meets agent state management.

New paper at ARCS 2026 in Mainz. We decouple agent planning from infrastructure actuation so that LLM-based remediation agents cannot cause more damage than the incident they are trying to fix.

Akhil Arora and I are running a half-day tutorial at SOSP 2026 on building and hardening runtimes for long-lived, tool-using agents.

When intent became the ultimate abstraction and code stopped being art. A future-looking backward scenario set in 2029.

When code becomes cheap to generate but expensive to trust, architecture shifts to minimize what must be trusted and maximize what can be verified. Three concepts explain why: the Rehydration Law, the Forkability Trilemma, and the Intent-Compilation Theorem.

My paper on using LLMs to canonicalize SQL queries for semantic caching in OLAP systems has been accepted at DOLAP 2026.

I released scode, an open-source tool that sandboxes AI coding harnesses and blocks access to your credentials, personal files, and sensitive directories. One bash script, works with any tool.

Saumya and I talked about LoRACode on a Ploutos AI live stream: how LoRA adapters make code embeddings better without retraining the whole model.

OpenClaw has taken the AI world by storm with 150,000 GitHub stars. What makes it work? Two simple abstractions that Apple, Google, and Microsoft somehow missed. A systems perspective on Peter Steinberger's elegant design.

A year ago I submitted an ambitious Emmy Noether proposal on modular AI systems. It was rejected. But watching the field evolve since then, I cannot help but feel that we were right all along.

As we close out 2025, it is clear that building reliable AI systems is fundamentally a systems problem. Context engineering, state management, and failure handling matter as much as the models themselves.
