I think the parent comment is saying it is fast in software on a modern CPU, but making tha into an ASIC would either be a) slow or b) expensive due to the 32-bit additions.
IIRC (I can't find it right now), when NIST had the contest for AES, AES hhad to run on low power hardware in the late 90s/early 2000s. This required things like everything to be fast on an 8-bit microcontroller.
