With a prevalence rate of < 2% (at least in Australia) this seems like an incredibly mathematically flawed take. Whilst a broad/blanket diagnosis isn't useful for making generalisations about individuals in that group, it's certainly societally useful.

All models are wrong, some are useful. Of course it has some utility, otherwise it would drop out of use on its own. The problem with big catchall symptom based diagnoses are what they drive focus towards and away from. I get that the scientific process has to start somewhere, by putting similar things in a bag, before it can tease out mechanisms and groupings. But when such simplistic models remain how doctors communicate with patients, it crowds out more nuanced understanding. Like even the word "spectrum", trying to add some depth to the pop culture model, is really just a fancy word for a single scalar.

I just disagree with this take.

For people with autism, the broad criteria help to serve as guideposts for common experiences shared by those with autism. When doing treatment, everyone gets into the specifics of what autism means for the individual.

What you are complaining about is similar to someone complaining that cancer is too broad of a term. After all, the word cancer describes a spectrum of mutations and symptoms everywhere in the body.

I don’t disagree that pop culture has distilled spectrum down into a magnitude, but that isn’t how the DSM describes it or how professionals diagnose it (or in my experience how they communicate it). The metaphor is supposed to be like the light spectrum not “less autism ranging to more autism”. Severity scale is distinct to interacting traits of social issues and restricted interests and repetitive behaviors (the spectrum bit).
