It's been switching over to PoS for years. I distinctly remember articles in 2019 about how they'd switch by the end of 2020, articles in 2020 about how they'd switch by the end of 2021, and here we are in 2022.
The point holds until they actually do make the switch.
We're now in the phase where public testnets of full PoS Ethereum are running [1, 2]. Ideally, we'll have the merge before the next difficulty bomb goes off in June.

Just not all of Ethereum is running PoS. All of Ethereum will switch over and it's currently planned for July.
Yes, there is also a PoS chain, confusingly also called "Ethereum", and yes it will soon become the primary chain, but that does not negate the fact that today nearly all activity happens on the PoW chain.
