Short, freeform field notes from Addy Osmani on AI, coding agents, and engineering. https://addyosmani.com/notes/ Addy Osmani Meta Superintelligence Labs shipped Muse Spark 1.1 this week. The turnaround is real and underrated, the pricing is a gift to developers, going closed is understandable but I hope temporary, and the benchmarks would benefit from published methodology. It was easy to write Meta off a year ago; Muse Spark is a reminder not to.

The open questions I most want to stress-test are day-long autonomy and the eval-gaming METR flagged.

Safety and trust are the area I most want to see mature, and I'm hopeful the governance story catches up to the engineering.

The classifier friction is a solvable early-days problem, the cost is a positioning choice, and my one firm ask is transparency. The capability is the story, and it's a big one.
