Can you give more info about Zero Knowledge Proofs would require ASICS?
"Type 1 aims to replicate Ethereum exactly, and so it has no way of mitigating these inefficiencies. At present, proofs for Ethereum blocks take many hours to produce. This can be mitigated either by clever engineering to massively parallelize the prover or in the longer term by ZK-SNARK ASICs."
...
"Personally, my hope is that everything becomes Type 1 over time, through a combination of improvements in ZK-EVMs and improvements to Ethereum itself to make it more ZK-SNARK-friendly."
In other words:
Switching to PoS, removes power allocated to GPUs for ethash mining. Adding ASICs for zk creates a requirement that doesn't exist today, for using power.
It’s like saying the internet needs more energy to run when a new application is developed. No, the internet is the same, it’s the application that now needs energy. So while the total energy the internet uses has increased, it did not increase the total required for the internet to exist itself.
