Totally agree. I really like the format of Talking Machines, which is :
- deep dive into nuanced topic like Latent Dirichlet allocation
- answering a reader question
- in depth interview with a luminary in the field (good mixture between "celebs" like Andrew Ng and lesser known, but still brilliant, practioners)
Talking Machines is definitely my favorite ML related podcast, the audio quality could be a bit better, but the hosts, topics, and interviews are really good, and I've used actually ended up actually using quite a few things I first heard about on the podcast.
Gentler Podcasts (still quite useful, but are approachable to those who don't read ML whitepapers frequently):
Not found AI/ML specific ones that I like yet
I like a16Z which often has good content on the wider sector though https://a16z.com/podcasts/
It's from the VC firm run by Marc Andreessen and Ben Horowitz, so they're well connected and often have interviews with founders and other interesting AI folk.
I'm also a big fan of EconTalk, which originally was primarily an Economics podcast, but these days has interesting interviewees from across academia and business. Quite often these sessions discuss AI ethics and the social/political/economic consequences of new technologies or trends - https://www.econtalk.org/
Not specifically ML, but I am a huge fan of SoftwareEngineeringDaily, which always features really prominent and poignant guests. Among others, they have a "Greatest Hits" episode about AI: https://softwareengineeringdaily.com/2019/01/31/architects-of-intelligence-with-martin-ford/
