  You don't have to employ AI/human differentiation (e.g. captcha) if you statistically mine user actions. I think that's where resolution is more likely to come from.

Step 2) Mine the actions of older accounts to detect patterns that point back to shilling. Not insurmountable.

  What will make Captchas valuable in the future is their ability to act as signatures, verifying you, the owner of the account, were physically present when you did whatever action required verification. They will not just be roadblocks, but checkpoints verifying not just that you are human, but that you are the person you claim to be.
