@Fiona I'm not sure do I understand correctly, but the average number of bugs didn't change over time. It is still approx. 1 bug per 100 lines of code. 😉 The problem is the size of modern software. 20 years ago, Linux, the kernel, has around 500k lines of code. Today around 30M. Performance, that's the Wirth's Law: https://en.wikipedia.org/wiki/Wirth%27s_law 🙂

We still do that things, just they didn't get their legends yet. They are too new. 🙂
