Whilst that's definitely great, my guess is that 90% of the people who would be interested and don't live in London, would not move to London for the job, even with a free Visa. Not supporting remote work therefore loses out on a majority of the potential talent pool for this job.

Is there any option for remote work? I'm sure there's plenty of people in less wrong who would live to work on alignment at deep mind, but don't happen to live in London...
