Not much has changed in the most recent (and hopefully future) editions
of TAoCP, apart from the underlying processor architecture and the more
sleek assembly language:

I can't say much about the coding quality of TeX, the program, having
personally dealt only with the excellent work by others done already in
Web2c and TeX Live, hiding the nitty-gritty stuff behind a simple
'make', but other Knuthian codes -- including SGB and MMIX, though both
written in CWEB and published in dead tree form -- leave a lot to wish
for in terms of "industrial strength".  ;o)
