It is not a reason to not learn about photography.
If everyone gets the same life experience, then nobody has the unique experience that makes one person stand out from the crowd.
One day, this autistic kid is going to be the only one who realizes a simple optical solution exist to solve a problem when everyone else is trying to use software. He'll make a fortune and he and his dad will live happily ever after.
I know a young guy that leaned how to knit when he was young - talk about an ancient art. He invented a cable-handling system for powered gantries (3D printers and such) because he thought of rope a bit differently than everyone else on the team.
If his dad knows about photography then photography suddenly makes a fabulous hobby because they can do it together. Could you please explain how "something modern" hobbies like playing candy crush, vaping, or on-line poker are better than photography?
