I doubt it, china's very own CBDC isn't build on Ethereum and for the hate that's still alive against crypto many CBDCs might be standalone, fresh blockchain of sort, this is the government we talking about here.
As for the video, the guy said PoW is what makes BTC so special and neutral, for me it's a big mistake that Ethereum is leaving behind something that bring the project this far, I hope things works like the maker dreams.
