I’ve found this too but I think audiobooks still have a place, they just can’t something you rely on being able to perfectly understand. A second book on the same topic or something in a topic loosely related but interesting. Or fiction to help stay awake on long road trips.
It's likely the same for me, but I tend to relisten to audiobooks I like, sometimes dozens of times. I have a hard time focusing on physical books, and I've probably only re-read a handful of them, so the net effect is that I take in more with a good audiobook.
I used read a lot of books when I was younger, then slowly stopped, and found getting back to reading quite hard as well. Armed with the knowledge that I used to be able to do this, I just forced myself to. And after a while, I found I had no trouble committing any more.
I used to do manual labor and I would work my way through like eight hours of audiobooks per day.
