We do not know this and social progress can't be taken for granted. We've seen many countries regress rapidly when totalitarian regimes (especially theocracies) got their foothold in power. Directly (Iran) or by proximity (Poland).
It's a naive story of the 90's that social progress is always upwards. Liberalism both social and economic is definitely on the back foot.
Despite the current drama I do believe that in the long term today's culture wars will sound just as quaint.
The legal argument for in Loving v. Virginia was the same argument that was rejected when Roe v. Wade overturned in Dobbs. Thomas actually calls out the other major cases, basically asking for a chance to overturn those as well, specifically Griswold, Lawrence, and Obergefell. He's not going to overturn Loving given that hes in an interracial marriage himself, but whoever replaces him when he finally retires might, and he would have done all of the work getting case law to that point.
