If the ad blocking becomes so widespread that the ad-supported model becomes unsustainable, I think a lot of people will be unhappy with what happens next. There will be a lot more paywalls and a lot more native advertising, which will be fine for entrenched players but much harder for very small publishers to pull off.
The cool thing about AdWords was you could write a little blog and actually make a few dollars running ads on it just by adding a snippet of code. Maybe micropayments can take care of that some day?
