Finally, if you are so convinced that PoW is the end of Bitcoin, let us know what the alternative is. If it is PoS, well... PoS already exists, so just go use that instead of trying to change something that some of us think is working just fine. I've also advocated for a PoS fork of Bitcoin itself. I would love to see it compete head to head with the original PoW.
I always assumed that was a sarcastic thought experiment where you get to double your holdings (of PoW Bitcoin).
One thing I don't get with all these threads is why Bitcoin proper would be expected to drop it's one defining characteristic. We are currently conducting an experiment to find out if distributed consensus is even possible in the face of well-funded adversaries. To change the consensus mechanism mid-stream would invalidate the experimental results.
I understand that the PoW opponents think that PoW will eventually fail. If/when it does, we can learn from how much damage is actually done during the attack. Bitcoin is designed in such a way that any attack has to be ongoing to be effective. With the "Nothing at Stake" problem in PoS coins, the attacker needs only the majority of votes at a single point in time.
It wont fail it will just become irrelevant, you can still use myspace.
