But what if I want a faster horse?

For any given thing or category of thing, a tiny minority of the human population will be enthusiasts of that thing, but those enthusiasts will have an outsize effect in determining everyone else's taste for that thing. For example, very few people have any real interest in driving a car at 200 MPH, but Ferraris, Lamborghinis and Porsches are widely understood as desirable cars, because the people who are into cars like those marques.

If you're designing a consumer-oriented web service like Netflix or Spotify or Instagram, you will probably add in some user analytics service, and use the insights from that analysis to inform future development. However, that analysis will aggregate its results over all your users, and won't pick out the enthusiasts, who will shape discourse and public opinion about your service. Consequently, your results will be dominated by people who don't really have an opinion, and just take whatever they're given.

Think about web browsers. The first popular browser was Netscape Navigator; then, Internet Explorer came onto the scene. Mozilla Firefox clawed back a fair chunk of market share, and then Google Chrome came along and ate everyone's lunch. In all of these changes, most of the userbase didn't really care what browser they were using: the change was driven by enthusiasts recommending the latest and greatest to their less-technically-inclined friends and family.

So if you develop your product by following your analytics, you'll inevitably converge on something that just shoves content into the faces of an indiscriminating userbase, because that's what the median user of any given service wants. (This isn't to say that most people are tasteless blobs; I think everyone is a connoisseur of something, it's just that for any given individual, that something probably isn't your product.) But who knows - maybe that really is the most profitable way to run a tech business.

Nice example, but not everything is like automobiles where probably not even one in 1000 people has ever been to a track day let alone actually raced a car, but sporty marques are desired.

A very large portion of people actually cares about what they are searching for, and want the ability to ACTUALLY search and find that, with real parameters, not merely get some not-even-close stuff shoved onto their screen instead. That is NOT the serendipity of browsing the stacks in a great library.

A great example of failure is Amazon. I run a small design & manufacturing business, and years ago started getting pestered by Amazon about "Amazon Business" trying to supply both office staples and parts to businesses. This was an area that had enormous potential. Yet, they have entirely failed. I've never bought a single item, and it has faded.

Their primary competitor is McMaster-Carr [0] who does it right. Well-defined categories of everything, and highly specific search capabilities, at reasonable but not bargain prices. EVERYTHING you might search for is fully parameterized in every dimension and feature. Min/max/exact, width/depth/height/thread/diameter/material/containerType/etc./etc./etc. appropriate for each type of product. The key is McMaster DOES NOT WASTE MY TIME. I can go there, quickly find what I want or determine that they don't have it, and get on with my day.

The smaller company that does it right is still beating the tech giant a decade later. Same for other similar suppliers who actually have a clue about what their customers really want.

They continue to prevail over tech giants and VC-funded sites BECAUSE THEY ARE NOT STUPID.

It would be nice if the tech/vc crowd would also stop being stupid. They started out not stupid, but they really lose the plot when they think a few extra eyeballs this week will really win in the long run. At least provide two modes, a strict and serious search and their new messy UI. But they are stupid and this will not happen. Enshittification rules the day.
