What is human-level intelligence is a normative and philosophical question, which means it will not be resolved in some objective manner. There's no requirements for us to know, there's only requirements for us to propose in the form of norms.

The only approach we will be able to claim objectively can produce systems with human-level intelligence is procreation.

This kind of reminds me of the history heavier than air flight and those that thought it wasn't possible along with those that thought it would only be possible by flapping like a bird.

Of course over 100 years later we know it's not only possible but manned flight is far more capable than natural flight in almost every metric.
