Is it possible to become autistic when you weren't born autistic?

I used to be very charismatic and had lots of friends but then I started playing minecraft and a couple of years later I think it's possible I became autistic from hanging around so many other autistic my brain absorbed their cancerous autism and it spreaded to me.

Is this possible?

Yes brain damage

No.

No. The "(whatever, mine, war,)craft" games just make people stupid.

You can't develop or catch autism.
