Every company is rushing to build intelligence into their products. AI layers, world models, agents running in the background. And most of them will get it wrong.
Not because the tech isn't good. Because the input isn't.
The intelligence is only ever as good as the signal feeding it.

And right now, almost nobody is thinking seriously about where that signal comes from, how it's collected, how it's structured, and whether it actually reflects real human experience.
That's the gap. And that's what I'm calling the Human Signal Layer.
It sits underneath everything else. Before the intelligence layer. Before the world model. If those two layers are the brain, the Human Signal Layer is what the brain eats. Feed it junk, you get junk answers. Feed it real, structured, high quality human signal and suddenly your product decisions are being generated by your users, not your assumptions.
In a world where every product team has access to the same AI tools, the companies that win will be the ones who figured out how to listen better.
That's the layer almost nobody is building yet. And it's the most important one.
