There are two problems here: The first is that a lot of ethereum talk is just that; hot air with little substance.

The second is that PoS has significantly worse security properties than PoW.

The core reason is that "changing your mind" (rolling back the blockchain) is free with PoS, except for possible loss of value of the cryptocurrency, whereas it's extremely expensive with PoW. There are all sorts of band-aids you can slap on like ignoring block reorgs of a certain depth, but then you lose properties like network partition tolerance.

We shipped ethereum proof of stake December 1st, 2020. There are over 100,000 validators in the network, securing over $6 billion worth of value. This isn't hot air with little substance.
