On the AT I have done a lot of SOBO hiking past hundreds of thru hikers on all parts of the trail, and I think it's a real mix.
Many drop out fast because hiking wasn't quite the experience they thought it would be.
Many gamify the trail, and focus more on aspects other than enjoying nature. eg: trudging along and trying to be as social as possible, messing around with your go pro, etc. Obviously those can be done in conjunction with enjoying the trail as well
And some seem to just be loving being out there.
For many other LD trails, it seems to be a much higher % of people who love to hike.
The only way I would be able to thru the AT at this point is if it was an alternate timing/route. eg: sobo start Sept 1, hiking long days, which I enjoy. All the clutter on that trail doesn't work for me, since I do actually like hiking.
I suspect this site, and particularly people that would respond to this thread, has a majority of people that actually like to hike..
