On the other hand, the dwarven race, if you caare about that sort of species survival sort of thing, is going to survive. I'm not too clear on how Dwarf-Human unions happen, but there's clearly an established and sustaining Dwarf diaspora.
Elves, on the other hand, are on a demographic glide path to extinction. If human societies reform to the point that elves can integrate, then elves marrying humans will end the elves. And if Elves refuse to integrate and remain ostracized and divided like the Dalish, then they'll gradually die in small groups even as the humans continue to grow larger and outnumber them.
Short of someone like Solas finding a way to magically uplift humans into elves, the only way for elves to outlive humans is total genocide.
(Which would be bad, lest we have to remind some people who have advocated such in the past.)
Personally, I'd be fine with Solas trying to 'fix' the world once again by doing something that starts allowing random children to be born as elves in some sort of 'the magic comes back' scenario. It'd be interesting, if not gentle and benevolent for everyone involved.
