Charles Hoskinson has been vocal about Ethereum's future. He criticizes its complexity, governance issues, and scaling struggles.
He argues Ethereum’s survival over the next 10–15 years is at risk due to:
Technical debt (layered upgrades without a fresh foundation)
Centralization risks (post-proof of stake)
Slow, messy governance
Stronger competition (Cardano, Solana, etc.)
Keep in mind, Charles is also biased — he left Ethereum on bad terms and now competes with it through Cardano.
