I think our understanding has changed.

Computers haven't really changed much in the last few decades either.

Well, when they were DILs with 0.1 inch pitch I was happy to mod them.
These days I can't even see the devices.

Manufacturing has changed quite a bit.

Apart from scale, less than you might think. SMT vs through-hole was a
jump of course, but since then only the scale has changed much.

Disclaimer: I didn't go in many manufacturing plants between ~1990-2010.
