People don't like to write tests so any argument saying you need fewer of them goes down real smooth. The details don't matter so much. But when software actually needs to be made at scale and with high quality you almost always have lots of tests. Statistically, the average developer is not writing software anymore where corner cases matter. They're writing various permutations on standard web apps. Most web apps are pretty buggy, even ones from major corporations. So stakes are relatively low for having failures. People writing file systems or crypto routines are going to have an easier time understanding the value of tests.
