This is exactly my point. :) Bitcoin is not state of the art anymore because the innovation it brought to a specific problem evolved into something more generic, namely smart contract platforms. However, the implementation of such smart contact platforms (which arguably won't even use Nakamoto consensus, the core innovation, upon their mainstream adoption) wouldn't be possible without the initial innovation of bitcoin.

By the way, why do you say "unfortunately"? Isn't it a good thing that new protocols are being built for new ideas? It would be sisyphean to keep mending old protocols that were designed for a different purpose.
