According to ChainCatcher, Ethereum co-founder Vitalik Buterin posted on the X platform that "by default, we should actually be skeptical of buzzwords like "smart" because historically, it has often been a way to package centralized control, data leakage, and other issues in a cool way (see many "smart home" products).

Ask specific questions. Does the design of the wallet really expand the boundaries in protecting users from centralized malicious behavior and their own mistakes? Well-designed wallets do this. Poorly designed ones may have the opposite effect."
