It's not new scientific ground but a machine beating a challenging computer science problem unassisted is a big deal. If they can do that then there are a lot of other challenging things they can do.

Like what exactly? As far as I can tell, the drug discovery is fizzling out, so it's not talked about much. Toxicity, for one, is a big problem, and the AI is not going to tell you whether the new drug it just concocted is suitable for humans or not.

Small model solves an easy problem; big model solves a challenging problem. I wouldn't call those problems; they are more like invented puzzles. Perfect match for the AI marketing department to "solve".
