Certainly does! We’ve had expert systems and various AI techniques for decades that weren’t efficient enough to run even though theoretically they would yield answers.

And even though solutions to many such problems were in the NP or NP-hard categories it didn’t mean that we couldn’t get useful results.

But it still gave us better results by applying what we know about search strategies and reinforcement to provide guidance and heuristics. Even Alpha didn’t use the most general algorithms and throw hardware at the problem. Still took quite a lot of specialized software and methods to fine-tune the overall system to produce the results we want.
