The Thirty Million Line Problem 

A historical argument for creating a stable instruction set architecture (ISA) for entire system-on-a-chip (SoC) packages.
Please note that although it's never mentioned in the audio there was a typo in the slide deck that makes the situation even more ludicrous when comparing 1990's machine to 2015's: the hard drive line erroneously said "gig" for the 1990's machine. It should have said "mb". The specs were the A3000, which never had any hard drives even close to 1 gig, let alone 50 gigs!
