The founders of the field left no doubt that their goal was, indeed, human-like intelligence, so the position you are stating here was the original goalpost-shifting.

There is nothing wrong with those original ambitions, and it is to nobody's discredit that progress has been slower than originally hoped (the same could be said in many other fields, from space travel to curing cancer.)

One can certainly find people (though not usually here) who insist that everything achieved so far is "just database lookup" or "just a machine doing what a person programmed it to do", and who leave little doubt that they would continue to do so regardless of what had been achieved. There are also philosophers who make more sophisticated versions of the same argument, such as by imagining p-zombies, which are unfalsifiably merely faking intelligence. Such people want to take the goalposts off the field, but the rest of us should be able to discuss what has been achieved, and what remains undone, without being distracted by arguments over the precise semantics of the phrase "artificial intelligence."
