Unironically the best advice we could ever give to young autists and young people is unapologetically stick with your niche hobbies and interests no matter what because you have NO idea what the future holds.
All those things that are currently cringe today could be full careers tomorrow. People had no idea streaming could be a profession, esports would be a real career, people could make livings off of filming their D&D campaigns, fake internet money would be in the United States National Strategic Reserve, people messing around in FruityLoops (FL Studio today) would give birth to an entire genre of EDM music, etc. etc.
All these things were cringe and mockable by others when they were in their nascency. Now kids today write them down as what they want to do or be or have when they grow up.
You have NO idea what the future holds, you have no idea when your unique quirks will be invaluable to the world. Don't throw away your spark, don't have shame over your interests, unapologetically pursue them over years and decades, don't listen to those who can't understand the future, and you have no idea how well you may be positioned come tomorrow.
