Ethereum to perform what some call "open heart surgery" on its core architecture

Ethereum has been "all things to all people" for the past few years, supporting tokens, dapps and many other use cases with a "swiss army knife" ethereum virtual machine (EVM) architecture that doesn't provide the long term flexibility that the vast potential and demonstrated developer activity of Ethereum will require. Many Ethereum developers have said that the protocol feels as if it was designed by computer scientists rather than Silicon Valley-style product developers. As a result, the EVM is being deprecated and replaced with WASM, or WebAssembly, code that is purported to be more flexible. The key thing to watch: whether Ethereum can make the upgrade while maintaining stability, security and continuing to scale a blockchain that thousands of developers and applications depend on daily.
