I hope I am not alone in looking to the future.
A wise and admirable ambition.
But I would echo the consideration that needs change in unforeseeable ways, and it is neither possible nor conducive to restful sleep to try to plan for all contingencies.
The other way of thinking about it is that there are many points along the way at which it will be possible to change the trajectory. As long as your child's well-being is carefully monitored by those who care for her best interest (a point on which I feel pretty confident we can rely!), the likelihood of something irredeemably bad happening because of her educational situation is relatively small.
So do your research, plan, and examine the options. But don't cause yourself too much anxiety trying to map out the whole path now.
On the question of who visits this forum, I would agree both that the population is probably enriched for those with some kind of need, and that one might expect that those needs would be different, so some might be able to share positive experiences as well.
