Pathologizing autistic behaviors is not the right approach here. Most autistic behaviors are harmless except insofar as allistic (non-autistic) people provide unnecessary consequences for it and through incompatibilities. We don't say that a Linux workstation in a network of Windows computers is broken or needs to be fixed (or visa-versa), but rather we recognize that the problems are due to the differences. As such, attempts to "cure" or "prevent" autism are actually an eugenic attempt to remove harmless variation that many people irrationally deem to be objectionable.

For example, it is commonly stated that autistic people have communication deficits, but this is just a communication difference. We can see this because if a communication task is given to a group of only autistic people they perform comparably to when the same task is given to a group of allistic people. Problems only take place when the group is mixed with both autistic and allistic people being present. The keyword "double empathy problem" can be used to find more information about this. (https://doi.org/10.1177/1362361320919286)

As another example, allistic people tend to very harshly judge autistic people for extremely subtle cues that they are different. When allistic people are shown recordings of autistic people communicating and of allistic people doing similiar tasks they, within less than a second, judge the autistic people very harshly. This effect persists when controlling for the content of the communication. (https://doi.org/10.1038/srep40700) Of course, doing anything that actually warrants such a judgement in a context like that is impossible so this is a bias against autistic people. I think that this can be compared to implicit racial bias: it is something that most people need to learn to consciously identify and then not perpetuate and is not due to any faults with the victim.

There are higher support needs autistic people who need help with activities of daily living. In my opinion, though, in many cases this is not autism but rather autism with an accompanying intellectual disability and the intellectual disability is the reason for higher supports needs. In some cases this could also be caregivers unnecessarily pathologizing behavior and then convincing someone that they need more support than they really do, which I have seen in real life.
