I think you are assuming that weak AI is being touted as strong AI.

What has happened is that methods have been discovered to do many very useful things using weak AI that have significant useful applications.

However, since it's weak AI the building blocks aren't that different from the AI we've had for decades. What makes it novel and worth its own academic specialization is that understanding how to combine and utilize those building blocks is not trivial.

I'd argue that it's currently a bit more of an art than a science, but surely it will eventually become a science.
