Bitcoin’s Climate Problem

I think its a form of therapy for the nocoiners. They can be safe with their delusion that 'thank goodness I didn't get involved in such a shady business! its destroying the planet.', while tradfi continues to commodify their life, and central banks print away their life savings.
The hashrate is ultimately what secures Bitcoin and is completely independent of transactions processed. A better comparison would be the Bitcoin hashrate vs. the human life, electricity, and resources spent securing gold vaults and other physical assets.
Proof of Work is not necessary to achieve this. Many blockchains already exist without it. Ethereum will, in theory, be moving away from it within a couple of years.
I'm scared that Bitcoin will never change or reduce its energy consumption despite the existence of eco-friendly alternatives. The definition of "Bitcoin" seems to be controlled by the miners, who will be the last ones that want to move away from an energy-intensive mining process.
What can be done to stop this?
Let it go. Energy will be used. Money will be made. You will be free.
Assume for the sake of argument that an alternative to Nakamoto Consensus is developed that meets your standards for security/decentralization and requires orders of magnitude less energy. Perhaps you're right and no such system exists today, but I'm not ready to accept that such a thing is physically impossible. Would you support hardforking Bitcoin to use the new system?
My concern is that miners never will, no matter the merits of switching.
Do I trust the universe of math more than I trust the universe of humans? Yes.
I don't believe this is a way of validating the security of a blockchain. Consider the turkey problem as stated in "THE BLACK SWAN" by Nassim Nicholas Taleb: "A Turkey is fed for 1000 days by a butcher. Every day confirms to the turkey (and the turkey's economics department, and its risk management department and its analytics department ...) that in fact the butcher loves turkeys. Every day brings more confidence to the statement. Until one day the Turkey is ripe for Thanks Giving".
You may very well be correct but I don't think length of time without a fatal error is a valid metric.
For me personally, I am in the Bitcoin proof-of-stake camp however I would be lying if I didn't say I also have a position in Ethereum.
My concern is that no matter which criteria we pick, and no matter how well PoW alternatives perform according to those criteria, miners will never vote to migrate. Bitcoin proof-of-stake would be great, but my concern applies equally to any potential eco-friendly alternatives, whether or not they've yet been invented.
I work in the Ethereum ecosystem but my continued support is entirely dependent on the PoS migration... and the same factors that make me nervous about Bitcoin make me nervous for eth2. But I hope they pull it off.
Bitcoin has survived bugs, attacks, forks, bans, smearing... and it all just made it stronger. Antifragile, although very volatile.
