There have been a couple others that come to mind.
With the CEO of Cerebras (a buzzy and well-funded chip startup) on the ARK Invest podcast: https://ark-invest.com/podcast/cerebras-wafer-scale-engine-a.... I will say that the interviewee here was a little bit more coy, and the podcast generally is geared more towards a business audience, though they have had very top tier technical talent on.
Any other tips for interviews with similar architects?
