🤣 No! 

Ethereum is alive and well. It is currently the most popular platform enabling developers to build and deploy decentralized applications. It is extremely popular with developers worldwide. Ethereum transitioned from Proof of Work to Proof of Stake in 2022, helping make it more efficient, sustainable, secure and scalable. This move will also reduce the ETH supply on an ongoing basis. Ethereum is under constant, active development and is very widely used.

So, no, Ethereum is not dead!
