I've been reading variations of the line "Ethereum is only weeks/months away from Proof of Stake" since probably early 2019.
Also doesn't Proof of Stake introduce another set of problems?
No, you haven’t. POS was, at best, a year plus away in 2019. No one credible was suggesting “weeks” back then… the beacon chain wasn’t even close to live yet.
ETH2’s beacon chain launched in Dec 2020 successfully, and has been running over a year in parallel with tens of billions in staked currency protecting it. This launched on time. The plan was originally:
1) beacon chain
2) sharding
3) the merge
The merge is when PoS takes over for PoW. The roadmap was changed in mid 2021 to push #3 before #2. That’s what’s about to happen, and I would even now put it in “months” . It won’t be “weeks” until a merge block # is announced, which will itself be weeks after the announcement of a successful testnet campaign (often multiple).
That's the main problem when it comes to this topic, isn't it?
The bellow comment calling it “vapor ware” is ignorant.
