Whether autism is genetic is not related to the question at all. More people are diagnosed with autism because we have better tests now than before and we test more kids.

And finally we also broadened what is considered autism.

Could you explain a bit? I see main issue with Signal (though I’m not an expert, and they’re not strictly related to security): it’s centralized (and the server isn’t even open-source).

The question is also a lot about your threat model right?
