Almost all of the avenue trees in my neighborhood were Ash, most around 50 years old, and they were all taken down last spring due to the borer. Limbs had been falling for years during storms, we were pretty worried about seeing significant damage due to the trees literally falling apart over our house. When they were taken down, most of the stumps were soft enough to crumble with your fingertips and the sapwood was completely webbed with borer holes.

About a month after they took the trees down, we had the worst thunderstorm in years. Lost power for three days due to dozens of uprooted (non-Ash!) trees. I can't imagine the carnage had those trees still been up.
