If I spent 10hrs a day for 365 days in a row I wouldn’t get through my backlog (easily way over 500k photos), but that’s not really the point. I don’t need to process and post every photo I take, many are either just for me or alternate takes that I might want someday. Looking through photos I took 10 years ago is one of my favorite activities and I often find hidden gems that I had dismissed before in the moment when originally gone through.
I do the same thing, I follow Johnny Harris' method[0] mostly. Basically I pick a random date (or an iOS provided "memory") and go through a bunch of photos related to that event. Then I delete all the useless ones, like the 99 takes I did of a sunset, and just keep the best ones.
