You haven't seen "off the deep end" CISC until you look at the Intel iAPX 432,
which makes the VAX architecture look lean and mean.

For that matter, VAX was far simpler than x86 and x86_64 have become.

And I wouldn't argue that it's CISC, but even the ARMv8 architecture manual is
over 2000 pages.
