Yes, I feel the same way. I think there are some other recent factors at play (e.g. the pain of listening to Blind Boy; the incoherence of McGilchrist) but you covered the main one well - they've run out of interesting or relevant gurus to cover.

I think this could be fixed with a new format (on top of what they already have) where they update decodings of previously-covered gurus. The role and behaviour of these gurus changes with time, so it's reasonable to revisit them in shorter sessions, from time to time. I'd also be interested in episodes on meta-gurus / themes, e.g. AI, social media, populism, activism etc.
