A number of things might change, e.g.
As you get older, you mellow out more, learn to copy other people's behaviours more, appreciate people's company more, learn to share interests, and so on.
I know from personal experience that judicious use of certain drugs (especially SSRIs and anti-anxiety meds, and sometimes stimulants) can alter your brain chemistry favourably.
You find a job you're good at, end up being able to support a family, and you no longer care about being 'autistic' - most people will just see you as an eccentric, clever person, if you happen to be working in a good job.
But none of these things are set in stone.
It ultimately rests on whether you can be comfortable with who you are; as soon as it no longer upsets you that you are autistic, you can just stop caring, and get on with doing what you like to do.
There are people who can help you - you just have to be receptive, open, honest, express yourself, and learn to love others .... and eventually you learn how to love.
