Wishing there was a prevention and cure for autism and other disabilities

Hello I am hoping for the future in this world that there would be a possible cure for autism and all types of disabilities as I really hate seeing people with disabilities all the time because it makes me a bit angry that it has happened to them and it makes me feel sorry for them as I really want everyone to be the same for once and for everyone to understand when I really want treatment to be out there and also for more hope for all blind people to be able to see for once.
