It’s been mentioned in passing but rim brakes by their very nature destroy a major part of the wheel. I live in the north of England in a very hilly area - getting 2500m ascent and descent on an 80km ride is normal and 20% grades are not uncommon and there’s a lot of cr*p on the roads. I’ve replaced two wheelsets on my current road bike purely because the rims were totally shot and due to modern pricing systems it was as cheap to buy new wheels as it was to replace the rims and rebuild the existing hubs into those.
Another benefit of disc brakes is that if you break a spoke and your wheel goes out of true by more than a few mm then you don’t need to open up the brake so you can still ride and you still get the use of the brake.
Disadvantages : they pick up oil and dirt off the road and squeal like a hog!
I think a lot of complaints about discs are as much about resistance to change as the technology itself. I moved to discs on my mountain bike as soon as I could afford to. Now the only bike I have without discs is my road bike which is semi-retired and will probably just stay on the trainer for the rest of its days. My next road bike will have discs.
