>That's completely irrelevant. Criticism is not about solving the problem. It's about pointing out that the current solution is inadequate.

Well it's a pointless criticism when everyone knows CAPTCHAs suck. People have spent a lot of time working on them trying to find better ones that work consistently at scale and have failed.

It's similar to someone now writing a criticism on the testing procedures at the Chernobyl nuclear power plan.
