Yes, and it's definitely impressive, and I know this might seem like moving the goalposts, but the market cap of Beacon is very small compared to ETH Mainnet. More importantly, it's not _the_ ETH blockchain. Beacon may be working so well because PoS is optional. The people participating in Beacon have bought into PoS on a conceptual level and are working to make it work. When you're incentivized to, you can ignore the pretty fundamental design problems of PoS.
Once ETH tries to get everyone into PoS, that's where I think problems start.
If ETH weren't so established right now through the NFT marketplace, I might suspect you'd see a jump to other blockchains, like Bitcoin, that are still on PoW. Since it is established, I worry that people will try to make it work for a few years, but it ultimately won't work, and ETH Mainnet will either be forced to revert to PoW or lose popularity to another fork.
