Stopping new models won't stop AI progress: today's models with tomorrow's harnesses

In a discussion with David Duvenaud and teortaxesTex, wfithian argues AI will keep improving even after we stop training new models: "we've not seen how capable today's models will be with tomorrow's harnesses, coordination, etc." — the same brains got cavemen to the moon. Duvenaud notes test-time compute scaling is a related channel, and gradient-free tuning of contexts and scaffolds would still enable a "poor-man's RL," just far slower. wfithian agrees.
