Ask HN: Why hasn't anyone fixed product search yet?

Every solution I've seen either:

1. Replicates Google's ad-driven model (but worse)

2. Claims 'AI' but acts as a black box

Yet we all waste hours daily on:

- Decoding fake reviews - Reverse-engineering SEO-optimized 'best of' lists - Cross-referencing Reddit threads from 2018

Serious question: What would it take to build a truly user-aligned product search engine?

Technical constraints? Business model dilemmas? Or is it just a hard problem nobody wants to solve right?
