An interesting one I know is ex-Anandtech CPU reviewer Ian Cutress's AI chips podcast[1].
Then he went on his way and I tried following him to see if he brings some quality independent content but it's so derivative. There's no deep insight, no originality. He's just reprocessing info from primary sources. At one point I felt like watching reaction videos and eventually decided to stick with those primary sources. I hope he finds his niche though.
