本日6月1日、メルカリのCHRO兼CAIO（Chief AI Officer）に就任しました。

これまでCTOとしてAI活用の推進を担ってきましたが、ここ半年ほど、AI-Nativeを抜本的に進めるには、組織変革を並行しておこなわなければならないと痛感していました。

そこでこの度、CAIOとして全社のAI活用の戦略と推進を引き続き担いつつ、それを根本から実行するための組織変革をCHROとして進めていきます。

AIのリスクを認識し、これまでHRが作り上げてきた組織をリスペクトしながら、大胆に組織変革を起こしていけたらと思います。

まだまだAI-Native Companyになるためにはやらなくてはいけないことがたくさんある！今後ともどうぞよろしくお願いいたします。

Dogfooding Opus 4.7 the last few weeks, I've been feeling incredibly productive. Sharing a few tips to get more out of 4.7 🧵

Es una locura. Estamos todos creando un vocabulario esperando entendernos pero hablando de cosas distintas.
No ayuda tampoco que todo cambie y evolucione cada mes, y que estemos bombardeados por contenido generado por creadores del mismo buscando y mezclando buzzwords por doquier

I have been a GM running D&D Campaigns for decades.
I can't explain how good Claude is as a GM assistant.
One day I should explain my workflow :D
Still very HITL but quite powerful

Gemma 4

[Demis Hassabis @demishassabis]

Excited to launch Gemma 4: the best open models in the world for their respective sizes. Available in 4 sizes that can be fine-tuned for your specific task: 31B dense for great raw performance, 26B MoE for low latency, and effective 2B & 4B for edge device use - happy building!

I liked this article from Block.
Very Jack Dorsey style.
Flattening organizations, evolving classic rigid roles and leveraging AI as the brain to fuel your organization is a good premise.
Block shared more insights about how are they going about it than many (myself included).
I loved the idea of the World Model aplied to an organization and I will likely use it for myself.
But getting the world model to properly provide accurate information about decisions and priorities in a large and active organization is far from a trivial challenge, and I think, as of today, technology is not mature enough.
But I'm sure it will be soon enough.
