## Nauti's Take

The move to subagents makes architectural sense, but the 'accessible to non-technical users' pitch smells more like slide deck than lived reality. Parallel agents mean parallel failure modes — without a solid evals framework, this becomes a debugging nightmare fast. The genuinely interesting question is how conflicts between subagents get resolved when they produce contradictory outputs. Promising direction, but the proof is in the production deployment, not the press release.
