Presumably you researched Bruce Lee by reading and consuming other media related to him, most of which is likely known by the AI models. They just don't have access to any novel idea that you generated, inspired by your research.
Regardless of their current inabilities, which you're correct about, there's no logical reason that in the long term they can't be similarly inspired by considering the same information and making new connections / conjectures just as you did.
We're making the same mistake that the people who dismissed the early airplane made. "That's a neat trick, but it's too limited and not robust enough to be very useful". Not considering how the technology would evolve from the Wright Brother's prototypes.
