Then the spectrum would refer to the magnitude of any vector in multidimensional “autism space”.
Two complex numbers can have the same magnitude & be very far apart. Assuming we stick to the positive/positive quadrant it's not so bad. This metaphor (which, the spectrum itself is a metaphor, making this a metaphor of a metaphor) is to a 2d space tho, complex numbers are much more comparable based on magnitude as a result
Only if their magnitude is large; the maximum possible distance between two complex numbers of equal magnitude is double that magnitude.
And this limit is independent of the number of dimensions in the space you're working in; no two equal-magnitude vectors are ever farther apart than opposite vectors are.
If you stick to the first quadrant / octant / whatever n-dimensional division of space where all coordinates are positive... I don't think the number of dimensions makes any difference there either? Any two vectors define a plane (or a line, or, if they're both zero, a point), so two vectors in a 500-dimensional space can't be farther apart from each other than is possible for two vectors in a 2-dimensional space. Those 500-dimensional vectors are already embedded in a 2-dimensional space.
Your last comment is completely incorrect, for a point at (1,1,1,....) each extra dimension adds a constant 1 to the euclidean distance, so that in 500 dimensions a point at (1,1,1,....) is around 22.4 units away from the origin, while in two dimensions it is only 1.4 units away from the origin.
How so? Your followup makes no sense.

You're comparing vectors of different magnitudes. You could equally object that (200, 0) is much farther away from the origin than (2, 0) is. That's true, but so what? You're still in a two-dimensional space.
Are you under the impression that the "magnitude" of a vector and its "distance from the origin" are separate concepts? They aren't.
If you're going to defend the idea that something I said was incorrect, maybe you should have some idea of what it was?
> Vectors with larger magnitudes have larger magnitudes than vectors with smaller magnitudes do?
Vectors with more dimensions have larger magnitudes than vectors with fewer components, for the same average magnitude of the components. The distance between the origin and (1,1) is less than the distance between the origin and (1,1,1) even though the components in both cases all have magnitude 1.
Is this related to something that's been said so far?

Obviously, I didn't. It was already there before I made my first comment. Look up:
>>> Two complex numbers can have the same magnitude & be very far apart.
The only thing we've ever been discussing is what can happen between vectors of the same magnitude. But if you want to discuss what can happen between vectors of different magnitudes... everything I said is still true! It's easy to construct low-dimensional vectors with high magnitudes, and in fact the construction that I already gave, of interpreting large vectors within a space defined partially by themselves, will do the job.
Are you considering what all of this is supposed to be an analogy for?
Suppose autism has different components, something like this:
https://getgoally.com/blog/autism-spectrum-wheel/
You rate someone on each factor using the same scale, e.g. a real number from 0 to 1, or a scale of 1 to 10. The scale is arbitrary but consistent.
Then someone whose "average" rating is 0.5 on a scale of 0 to 1 can be farther away from someone else whose "average" rating is 0.5 when there are more factors. On a linear scale two people both at 0.5 have distance zero. On a two dimensional scale, you could have one at (0, 1) and one at (1, 0) and then each of their averages is still 0.5 but their distance is ~1.4.
That's what we're talking about.
The next step is them doing a black knight and pretending they didn't put in the requirement by hand.

Here's what you were referring to:
>> If you stick to the first quadrant / octant / whatever n-dimensional division of space where all coordinates are positive... I don't think the number of dimensions makes any difference there either? Any two vectors define a plane (or a line, or, if they're both zero, a point), so two vectors in a 500-dimensional space can't be farther apart from each other than is possible for two vectors in a 2-dimensional space. Those 500-dimensional vectors are already embedded in a 2-dimensional space.
All of those statements are, obviously, true. What did you think was incorrect?
