Well said. These POW/ energy waste arguments are getting really old. They act as if there aren't existing solutions. Take Algorand for an example, which is carbon negative and (Pure) Proof of Stake...

Until you realize the largest two cryptocurrencies are still using POW. Also, let me guess, who has stakes in this Algorand thing you mentioned.

Not everything needs to happen immediately, Proof of Work isn't some existential threat to human kind and Ethereum is already moving to PoS.

It's still early days for blockchain/crypto world. Alarmist comments don't really add anything to the discussion.

I am willing to bet in 5 years time, the largest crypto currency will still be BTC and it will still be POW.

Maybe, maybe not. If you're worried about the climate change impact, you can start now by charging additional taxes on all energy consumption.

Why should cryptocurrency be singled out? Just because some people dislike it? We haven't done much about climate change and the big pollutants in decades, but as soon as cryptocurrencies come up, it's suddenly treated as an existential threat to human kind - I don't buy it.

If we are talking about climate change, time is quickly running out. So talking about wishful thinking while reality is actually other way around does not seems to be helpful.

Can you quantify the impact on climate change that PoW is going to have if we don't act against it immediately?
