Geoffrey left DeepMind to serve in government. For 2 years, he has done work of national and global consequence - at genuine personal cost.  It is the kind of choice more of the best technical minds should be making. Thank you, Geoffrey - Britain has been fortunate to have you!

The worry about sacrificing future career advancement is super fake, FWIW. People do worry about that, but like, I’m not that worried that I came out of this with a worse reputation and neither should others. :)

I left DeepMind to join the UK AI Security Institute as a Research Director in Dec 2023 and started in April 2024 (time for family travel, wandering around London, and interval arithmetic). The past 2 years have cemented AISI as my favourite job to date!

AISI is a hugely impactful place, especially for Research Director-level folk! We have a deep bench of excellent, driven talent; the ability to drive research on catastrophic risks or large-scale societal impacts that translates unusually directly into policy and action; …

Geoffrey Irving@geoffreyirving

I have mixed feelings! It is right for family reasons and I’m excited for my next phase, but I love AISI and will miss it! My reasons to join stand: safety progress is slow, coordination is under-resourced, and governments have a key role in coordination.

Thank you, Ian! It took Ian a couple tries to convince me to join, and I've very thankful you persevered. A shame in hindsight I didn't get to the right answer a few months earlier in summer 2023! ❤️

Likewise, Joseph! It was very fun to help you design and build out the Model Transparency Team, and it’s a neat example of how AISI mixes research (what techniques will work) with the risk mitigation story (how will the decision process handle uncertain scientific evidence). ❤️

…and lots of access to very senior government decision makers who want to understand AI and influence its course. Please reach out if interested! I will continue on in an advisory capacity at AISI and am eager to pitch interested folk. :)

@geoffreyirving sad to see you leave AISI, Geoffrey! Really enjoyed reading about your and Yoshua Bengio’s important work in @scmallaby’s Infinity Machine.

Hope your next venture will continue this important work.
