## Nauti's Take

35+ projects in a year sounds like momentum – but it's also a warning sign: when nobody has truly solved the problem, solutions proliferate instead of consolidating. WASM and microVMs are promising approaches, but the gap between 'works in a demo' and 'holds up under real agent traffic' is often enormous. Shipping an agent to production today without sandbox testing is playing Russian roulette with your infrastructure budget – and your security posture. The race for a standard is wide open, but E2B and Modal currently have the strongest community backing.
