I agree bitcoin should switch.<p>I also think it's never going to happen. Bitcoin is as static as it will ever get.<p>Arguing for proof of stake will only get the internet mad at you, not much technical discussion is even possible.<p>It could maintain proof of work and switch to argon2, thus eliminating the huge centralization of mining in ASICs and GPUs. But you can't touch the miners.<p>You could argue that smart contracts are great, and could integrate the latest and greatest now that we have done a lot of experimentation, but it's not going to happen.<p>There are improvements that could be integrated to have merely more transactions/sec, and not much has been done.<p>Technologically, bitcoin is dead. As an investment instead it seems to be going well.
