Faster and Lonelier: AI, Isolation, and the Erosion of Engineering Collaboration
AI makes individual engineers faster - and quietly more isolated.
As coding agents become everyone's default pair, the collaboration that keeps an org healthy erodes: pairing fades, context gets trapped in private chat histories, knowledge stops diffusing, teams drift into silos.
Velocity dashboards look great, so nothing seems wrong - until onboarding slows and bus-factor spikes.
This talk names the failure mode, explains why standard metrics miss it, and shows what leaders can do to keep teams connected as AI adoption accelerates.

From Metrics to Evals: What Hyperscale Taught Me About Observing AI Systems
Most of the advice on observing AI systems is being invented from scratch right now, and a good deal of it was solved a decade ago at hyperscale. I have spent years running observability on large distributed systems, and this talk brings that hard-won discipline to AI and agentic workloads. Classic observability assumes deterministic behaviour, clear pass or fail, and an error when something breaks. AI breaks all three, and the worst failures are silent, with quality degrading while the dashboard stays green. I cover which distributed-systems patterns transfer directly, what has to be rethought (new signals like tokens, cost and tool-call success, and tracing across agent and tool boundaries), and evaluation as the new form of testing, turning eval scores into SLIs and alerting on quality drift rather than just errors.
