If this was a solved problem, every e-com website would already run some variant of https://arxiv.org/pdf/2209.07663 for all their shopping surfaces and some version of "deep research" on every search query. They don't, so the problem isn't solved. And a big part of the problem is still the integration of behavioral, structured and unstructured signals into the underlying retrieval of products and content - which is what the article is about.

Also, the company is doing fine, not sure where that last sentence came from ^_^
