Change is needed sometimes and anything that is stagnant and not improving can be overtaken, so I would not be surprised if we see some future change in Bitcoin PoW or some better model, but it is certainly not going to be some shitty Proof-of-Stake.
Stagnant? Bitcoin doesn’t need to change.
But Bitcoin already changed many times, from P2PKH, P2SH, SegWit to Taproot which will be activated later in future.
Read his post. He believes a change in Bitcoin’s POW “or some better model” <- not sure what that means, will be better for Bitcoin’s future, and that he “will not be surprised to see that kind of change” in the future. Is he actually saying that Bitcoin must break what makes whole system work?
