Crypto Ai Agents

Can someone explain crypto Ai agent platforms like virtuals and ai16z. Are they just all hype ?
These agents are supposed to autonomously conduct transactions on and off the blockchain. One would assume they will augment pump and dump further. If you believe in crypto bros, then they are the agents of change. But then the entire crypto market is all hype and this is the next cog in the wheel.
 
They combine AI with blockchain to create autonomous systems that can trade, analyze data, and even launch projects. Virtuals focuses on co-owned AI agents, while ai16z is a decentralized trading fund on Solana.
