You should check out the Zero Knowledge podcast (https://zeroknowledge.fm/)
It's a crypto/blockchain podcast, but very technical, it's focused around the advanced technology that makes up the ecosystem (zero-knowledge cryptography, multi-party computation, consensus algorithms, miner-extractable value, new blockchain programming languages, etc).
Very technical, almost nothing about investing. The downside, some episodes may be a bit hard to jump into due to the technical nature.
