I've done a fair amount of research on the topic. It is also a significant part of my profession to understand fetal development. I view neonatal brain ultrasounds, CTs, and MRIs on a daily basis. So, to answer your concerns and questions regarding, "Is this an autism thing?", you have to have some basic understanding of what makes up an autistic brain. (I am realizing, at this point, I could write a book on the topic.) You can do your own research on the topic,...and as an autistic, I think it is important that we all do this for our personal education as well as our own mental health. Stick to scientific journals, as there is a disgusting amount of misinformation out on the general internet. Suffice it to say, there are areas of abnormal neuronal migrational patterns, some neurons that should look like "trees", look like "bushes", and vice-versa, the normal "pruning" of synaptic connections is altered, as is the programmed cell death (apoptosis). This can lead to a long list of asymmetric functioning and neurotransmitter imbalances. What a psychologist sees is asymmetrical functional abilities, sensory issues, behavior issues, communication issues, etc. IQs during testing can vary quite a bit from test to test,...significantly more statistical variation than when testing a neurotypical person,...a hallmark of autism.
Long story, short,...there are common traits that can identify individuals on the autism spectrum. Having said that, neurodivergence is one of those traits, and as such there can be a significant functional difference from one autistic to the next. What you must also understand is that many of us learn differently because of how we process our sensory information. A software program designed for Microsoft, or Android, will not work on an Apple product, and vice-versa. What may seem as someone learning something slowly or doing a task slowly, may be someone taking in and processing significantly more information, or perhaps entering that data into their brain in a different manner.
I have two young engineers as sons. One of my sons was married this weekend, and sitting around the table with his friends, I had a good laugh when someone had mentioned the term "weaponized autism". So, of course, I am doing some research on this term,...a term from almost a decade ago,...but more of a "deep dive" into this phenomenon began to show that even military units from around the world are specifically recruiting autistics for their special abilities behind computer screens, intelligence gathering, abilities to focus intensely on a project, etc,...skills that neurotypicals generally tend not to accel at. It's no surprise that many Silicon Valley software and tech companies specifically recruit autistics,...and the numbers of autistic children being born within that community is statistically quite high. I know many of us have difficulties with interpersonal relationships, but given the fact that there are over 100 identified autism markers on the human genome suggests,...if nothing else,...those genes are being passed on. A lot of people love autistics.
