No, I don't think so. By the time quantum supremacy is really achieved for a "Q-Day" that could affect them or things like them, the existing blockchains which have already been getting hardened will have gotten even harder. Quantum computing could be used to further harden them, as well, rather than compromise them.
Supposing that Q-Day brought any temporary hurdles to Bitcoin or Ethereum or related blockchains, well...due to their underlying nature resulting in justified Permanence, we would be able to simply reconstitute and redeploy them for their functionalities because they've already been sufficiently imbued with value and institutional interest as well. These are quantum-resistant hardenings.
So I do not think these tools or economic substrate layers are going anywhere. They are very valuable for the particular kinds of applications that can be built with them and also as additional productive layers to the credit and liquidity markets nationally, internationally, and also globally/universally.
So there is a lot of institutional interest, including governance interest, in using them to build better systems. Bitcoin on its own would be reduced in such justification but because of Ethereum's function as an engine which can drive utility, the two together are a formidable and quantum-resistant platform that can scale into the hundreds of trillions of dollars and in Ethereum's case...certainly beyond $1Q in time.
I'm very bullish on the underlying technology, even beyond tokenomics for any particular project. The underlying technologies are powerful protocols that facilitate the development and deployment of Non Zero Sum systems at scale. With Q-Day not expected until end of 2020s or beginning of 2030s, that is a considerable amount of time (in the tech world) to lay the ground work for further hardening and discussions around this.
