Vitalik Buterin believes that replacing the Ethereum Virtual Machine (EVM) with the RISC-V instruction set could be the only viable path to drastically improving the efficiency and scalability of Ethereum’s execution layer.

Quotes that support claims

Buterin said the ‘radical’ and ‘ambitious’ idea could be the ‘only viable path’ for significantly scaling Ethereum’s execution layer.

The beam chain effort holds great promise for greatly simplifying the consensus layer of Ethereum, but for the execution layer to see similar gains, this kind of radical change may be the only viable path.
