Forrest Hell, I Didn't Even See the Trees....!
This is from someone who has a rudimentary understanding of what's going on at the technical level, but understands ad lingo very well.
First, it's a natural marketing progression to continually increase the bit access number, and then use propaganda to generate the perceived need.
So, one argument would be that,"128 bit computing would be faster". This doesn't hold up the the light of current CPU architecture. Here, multiple core designs have increased the data manipulation rate exponentially, by parallel processing of data, and greater amount of function per clock cycle. Who's to say if those modifications have reaped all the rewards they can.
Wow, now that we have 128 BACs, let's hurry up and develop the 256 BAC!
With respect to the CAD proponent sector of this discussion; after something is designed, it has to be built and paid for, (or vice versa). A 128 (or 256) bit OS won't help with those aspects of the process. So, let's get cracking with those 256'ers, and all you engineers can hasten you compute to the unemployment line. "Whaddya mean the works all done". Of course there's always the possibility of being retrained to design 512 BA computers, but obviously the pay would be lower at the start.
In the real world there are applications for extremely fast computers that will manipulate very, very large numbers. For example, as of 5 years ago, our fastest machines weren't able to come close to modeling the events during the collapse and subsequent explosion of a dying star. As is always the case, there is a certain period of time before technology trickles down from applications in space, but I have no doubt that Madison Avenue will be able to show us how a 256 bit processor will be able to much better control our microwaves and programmable coffee makers. As the technology trickles down even further, the average welfare mother will be able to track the events within a supernova...! And really, don't they all sit around waiting for that opportunity...?
Another huge improvement reaped from from higher bit access computers will be in law enforcement, for verily we will be able to track a scofflaw with an unpaid parking ticket to the far ends of the galaxy.
But the impact of higher bit access will be most utilized and appreciated in the field of computer gaming. There you will be able to tune out the world more successfully than in any other time in human history. Great kings and even greater pharaohs weren't able to remain aloof from their duties and surroundings as will be the video gamer of tomorrow!
Gone forever will be concerns about global warming, food and water shortages, war, famine, pestilence and disease! All these things will lose their relevance in comparison to playing "WOW 13" on your 512 bit XBox! If the ad men are smart, (and you know they are because they've studied psychology), they will package this modern day miracle in a box shaped and decorated to look like a human a**. That way, when you're done playing games for the day, you can put your head up that and catch a nap..!
