Where could I educate myself on the vulnerabilities of PoS? It seems like for PoW, the vulnerability comes from variability of computing power of miners - if miners capacity dips for a few hours because of external events, attacker can use that opportunity and bring online a lot of resources to do a 51% attack.

Doesn't a PoS attack require 51% of coin ownership? How would an attacker obtain that without being massively rich to begin with?

There’s also the overall economic argument that Proof of Work is actually just the least obscure version of anything else: https://www.truthcoin.info/blog/pow-cheapest/

Overall I’d just argue that because PoS doesn’t involve external resources to create blocks, the cost of producing a block won’t be well understood and thus there will be opportunities for rent extraction - which we’re already seeing with Lido staking.

Great article, thanks!
