I don't think it's just an engineering problem - decades of research have failed to produce a convincing, general definition of intelligence, capability or agency. You can try to form proxy metrics by combining benchmarks, but existing benchmarks are flawed, and should be taken with a pinch of salt.

It's evident in the fact that every time AI has historically met certain thresholds (chess-playing, the Turing Test, fluent language), we play with them a little more and find out there's something still lacking.
