Come to think of it, there was very little that had more

DimBulb is certainly AlwaysWrong, but the above is simply bull****.
Perhaps in your little corner of the world you were still using
phenolic substrates too but others had moved on long before. We were
using upwards of a hundred layers (96, IIRC)

Hundred layers?

We must have a language difference, because that is not even
close to true in english.

In fact, I challenge you to find any 100 layer boards,
anywhere, ever... within the next 30 years or more.
