I am from Prepress area so I am biased too, but the same thing goes for Prepress.
All the automation and software makes Prepress job 10 times easier than it used to be.
It used to be manually stripping pieces of film to create chokes and spreads, than it moved to software.
I remember having couple of defaults for trapping than digging in with trapping tool to manually trap most if not all traps with software.
Now these days 99% of the jobs just go through without operator even thinking about trapping them (automatic trapping by software in PDF), that is how systems evolved.
I also remember spending tons of time dropping large impo proofs, now it's seconds/minutes to do on booklet proofer.
I remember manually mixing powders, sometimes for hours so I can do proper chromaline proof, it evolved to minutes sending PDF to Epson.
Don't get me wrong, I like where we are now, speed and efficiency in Prepress multiplied with all the software and hardware automation and upgrades.
What is the next step, no prepress?
At least that is what it looks like to me, if you have good MIS, good automated PDF workflow with all the other automated devices, all you need is client skills upgrades
