Just checked your link - yes, Phil's Lab is good, not aware of anything better for PCB design on YouTube. Maybe some of the Rick Hartley recorded talks he recommends sometimes, or perhaps some old EEVBlog videos would be worthwhile too.
But in general I agree, there's too much fascination with Arduino et al. that I think's mid/long-term harmful to those that stick with it personally.
