Intelligence is absolutely trivial to measure. You just make a huge pile of tests of mental ability, the more the merrier. It won't be very sophisticated, but you have an intelligence test. Intelligence is so easy to measure in a rough way that people have accidentally built intelligence tests when they were trying not to. A lot of the other critiques are at least somewhat suspect: Modern intelligence tests explicitly try to use tasks that you won't train yourself that much in in daily life and that try to eg. stress working memory capacity directly without testing for other skills. There's also evidence that training for some kind of skill like strategies for n-back numbers doesn't improve performance on similar tasks using letters, for example. Yes, it is not as good of a measure as a tape measure is, everyone knows that. But saying it's suspect and not useful is kind of like saying computer benchmarking is worthless and won't tell a crap machine from a powerful one.
