Discoverability is trivially solvable by dedicating journalists to products. There are already events the companies use to present their products, frequented by journalists who then proceed to write periodicals with new product categories, benchmarks and comparisons.

Those do get gamed and might cheat since they'd get kickbacks, but that should result in a reputation loss as other journalists point it out. There are also various cooperative models that work here well as members can just vote kickback-taking staff out.

People used to actually subscribe to magazines (and some still do) in areas they are interested in. And they still go and visit the shops to see if anything interesting pops up and there is word of mouth.

So I believe discoverability is not really a problem. The fact is that polished advertisements take up bandwidth that would be more productively utilized by a benchmark comparison chart with a commentary on differentiators. People would get more performant and/or better fitting products and services and the overall productivity and happiness would increase.

What you are talking about is marketing and advertising. You’re not solving anything.
